Briefly discuss if it would be better to operate with pumps in parallel or series and how your answer would change as the steepness of the system curve changes?

Answers

Answer 1

Answer:

1) In series, the combined head will move from point 1 to point 2 in theory. However, practically speaking, the combined head and flow rate will move along the system curve to point 3.

2) In parallel, the combined head and volume flow will move along the system curve from point 1 to point 3.

Explanation:

1) Pump in series:

When two or more pumps are connected in series, their resulting pump performance curve will be obtained by adding their respective heads at the same flow rate as shown in the first diagram attached.

In the first diagram, we have 3 curves namely:

- system curve

- single pump curve

- 2 pump in series curve

Also, we have points labeled 1, 2 and 3.

- Point 1 represents the point that the system operates with one pump running.

- Point 2 represents the point where the head of two identical pumps connected in series is twice the head of a single pump flowing at the same rate.

- Point 3 is the point where the system is operating when both pumps are running.

Now, since the flowrate is constant, the combined head will move from point 1 to point 2 in theory. However, practically speaking, the combined head and flow rate will move along the system curve to point 3.

2) Pump in parallel:

When two or more pumps are connected in parallel, their resulting pump performance curve will be obtained by adding their respective flow rates at same head as shown in the second diagram attached.

In the second diagram, we have 3 curves namely:

- system curve

- single pump curve

- 2 pump in series curve

Also, we have points labeled 1, 2 and 3

- Point 1 represents the point that the system operates with one pump running.

- Point 2 represents the point where the flow rate of two identical pumps connected in series is twice the flow rate of a single pump.

- Point 3 is the point where the system is operating when both pumps are running.

In this case, the combined head and volume flow will move along the system curve from point 1 to point 3.

Explanation:

The evaporator Temperature T1 = -10°C

h1 = 244.55kj/kg

S1 = 0.93782kj/kg

The enthalpy at second state from given condenser pressure from super heated refrigerant table

P2 = 600

S2 = S1

h2 = 267.19kj/kg

Enthalpy at 3 and 4 from condenser pressure

h3 = h4 = 81.5kj/kg

To get cooling load

QL = m(h1-h4)

M= 7

= 7(244.55-81.5)

= 7(163.05)

= 1141.35kw = 1141KW

COP

= h1-h4/h2 -h1

= 244.55-81.5/267.19-244.55

= 163.05/22.64

= 7.2

Answer:

Explanation:

The vander waals equation

[tex](P+n^2a/V^2)(V-nb)[/tex]=nRT

The factor n^2a/V^2 accounts for the attractive forces between the gases molecules whereas nb accounts for the decrease in volume occupied by the gas. Therefore, correct option would be  E. None of the above have BOTH of the two factors accurately stated

The correction of Van Der Waal to the ideal gas equation is that; real gas molecules exert forces on each other and that gas molecules have volume.

Van Der Waal (1873) proposed a modification to the ideal gas equation; PV = nRT. The ideal gas law assumes that molecules of gases do not have a definite volume but occupies the same volume as the container and do not exert any attractive forces on each other.

However, Van Der Waal introduced two major corrections to the ideal gas equation;

The gas molecules have real volume, V - nb gives the volume of the container that is inaccessible to the gas molecules.The second correction has to do with the fact that the gases actually exert an attractive force on each other. The real pressure of the gas is less than the ideal pressure of the gas which is captured in the term; P + an^2/V^2.

Hence, the ideal gas equation is now written as;

[tex](P + \frac{an^2}{V^2}) (V - nb) = nRT[/tex]

Signal loss is the reduction of a signal that occurs in a medium as a function of the physical length of the channel. This is known as:_________

a. degradation.
b. attenuation.
c. frequency degradation.
d. amplitude degradation.

Answers

Answer:

B) Attenuation

Explanation:

Attenuation can be regarded as the loss of signal strength which could be as a result of both external and internal factors. This loss of signal strength could occur in networking cables as well as other connections. Attenuation is a loss in energy, because as signal travels, its strength decreases as a a result of distance it covers, this loss of energy is due to the signal trying to overcome the resistance at the medium. One of the main the causes of attenuation is When there is Extra noise on available networks, networks such as electrical current as well as radio waves. It should be noted that attenuation is Signal loss which is the reduction of a signal that occurs in a medium as a function of the physical length of the channel.

Singnal attenuation can taken care of by using lower loss materials with high cost, instead of making of PCB routing length reduction. Amplifiers can also be engaged in amplifying attenuated signal to get back the original signal, this will compensate the loss.

Attenuation can be measured in decibels(dB), this gives the measurement of relative strengths of one signal at two different point or measurement of two signals.

(B) active state.
(C) passive state.
(D) both (B) and (C)

Answers

Answer:

(C) passive state.

Explanation:

The earth pressure is the pressure exerted by the soil on the shoring system. They are three types of earth pressure which are:

a) Rest state: In this state, the retaining wall is stationary, this makes the lateral stress to be zero.

b) Active state: In this state, the wall moves away from the back fill, this leads to an internal resistance. Hence the active earth pressure is less than earth pressure at rest

c) Passive state: In this state the wall is pushed towards the back fill, this leads to shearing resistance. Hence, the passive earth pressure is greater than earth pressure at rest

(C) 1.49×10^24 m^−3
(D) 2.57×10^24 m^−3

Answers

Answer:

C

Explanation:

N = Na.P/A------(1)

Na = avogadro's number = 6.02210²³

P = density

A = atomic weight of metal

When we substitute into equation 1 above we get

1.0x10²⁹atoms/m³

From here we calculate the number of vacancies

T = 1000⁰c = 1273K

The formula to use is

Nv= Nexo(Qt/K.T) -----(2)

Qt = 1.22eV

K = Boltzmann's constant = 8.6210x10^-5

When we substitute values into equation 2

We get Nv = 1.49 x 10²⁴m-3

Propyl Benzhydryl Ether (continued on next page):

(2) Based on the results of this experiment, write a mechanism for the acid catalyzed reaction of benzhydrol with 1-pentanol to give the product from the last question. (Note: the mechanism is written on the first page of this experiment. You just have to figure out, based on the experimental results, which alcohol is ROH and which is R'OH and the write it using those two alcohols.)
(3) Under milder temperatures than what is needed for dehydration, strong acids catalyze the self-condensation of 1-propyl alcohol to give di-n-propyl ether. The mechanism differs from that of today's reaction in that the protonated alcohol undergoes an Sy2 rather than an Syl reaction. Write the mechanism for the acid catalyzed condensation of ethyl alcohol to give diethyl ether. Note: make sure your mechanism has the following three steps (a) protonation (b) Sx2 (not Syl) and finally (c) deprotonation.

Answers

Answer:

See detailed explanation and image attached

Explanation:

1 mole of 1-pentanol reacts with 1 mole of benzhydrol

Number of moles in 1.5 g of benzhydrol = mass/molar mass = 1.5 g/184 g/mol = 0.008 moles of benzhydrol

x moles of 1-pentanol reacts with 0.008 moles of benzhydrol

x = 0.008 moles of 1-pentanol

If 1 mole occupies 22.4 L

0.008 moles occupies 22.4 * 0.008 moles = 0.179 L of 1-pentanol is required.

The mechanism of the formation of n-pentyl benzhydryl ether involves the protonation of the -OH group in benzhydrol. This is followed by loss of water molecule creating a carbocation which is attacked by the 1-pentanol.  Abstraction of a proton by a base completes the mechanism, regenerates the acid and yields the n-pentyl benzhydryl ether as shown in the image attached.

The synthesis of diethyl ether occurs by protonation of one ethanol molecule followed by SN2 attack by anothe ethanol molecule and a simultaneous loss of a water molecule. Deprotonation by a base yields the  diethyl ether

Yes, they are

Explanation:

A

Assuming that a glass piece is cooled from an elevated temperature, then the internal stresses which are also called thermal stresses, gets inroduced due to result of the difference in cooling rate and that of the thermal contraction that exists between the surface and the interior regions. They can lead to fractures such as thermal shock, as a result, we deem these thermal stresses important.

The process by which natural forces move weathered rock and soil from one place to another is called
a)soil conservation. b)deposition. c)abrasion. d)erosion

Answers

Answer:

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform.

 

Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. This transported material is called sediment.

Explanation:

Physical erosion describes the process of rocks changing their physical properties without changing their basic chemical composition. Physical erosion often causes rocks to get smaller or smoother. Rocks eroded through physical erosion often form clastic sediments. Clastic sediments are composed of fragments of older rocks that have been transported from their place of origin.Landslides and other forms of mass wasting are associated with physical weathering. These processes cause rocks to dislodge from hillsides and crumble as they tumble down a slope. 

Landslides and other forms of mass wasting are associated with physical weathering. These processes cause rocks to dislodge from hillsides and crumble as they tumble down a slope.  

Plant growth can also contribute to physical erosion in a process called bioerosion. Plants break up earthen materials as they take root, and can create cracks and crevices in rocks they encounter.

To attain maximum power delivered to a load, what value of load impedance is required if 1. the load can have any complex value; 2. the load must be pure resistance?

Answers

Answer:

Explanation:

Maximum power will be delivered to the load if

Z(load) = Z(t)*

If the Thevenin is defined as Z(t) = R(t) + jX(t), then the load impedance will be

Z(load) = Z(t)* = R(t) - jX(t)

Finding the equivalent impedance, we have that

Z(eq) = Z(t) + Z(load)

Simplifying further, we have

Z(eq) = R(t) + jX(t) + R(t) - jX(t)

Z(eq) = 2R(t)

Therefore, maximum power will be delivered to the load when Z(load) = Z(t)*

Maximum power will be delivered to a pure resistance table if

R(load) = |Z(t)|

Again, if we define the impedance of Thevenin, we have

Z(t) = R(t) + jX(t)

And therefore, our load resistance is

R(load) = √[R(t)² + X(t)²]

A soil with a cohesion of 25 kPa has a normal stress of 39 kPa and a shear stress of 56 kPa at the point of failure. The angle of internal friction for the soil is most nearly:__________.

Answers

Answer:

39⁰

Explanation:

We have cohesion c = 25kpa

Then the normal stress = 39kpa

Shear stress = 56kpa

This question is asking us to find the angle of internal friction

Shear stress at the time of failure = cohesion C + normal stresstanΦ

56 = 25 + 39tanΦ

Φ = angle if refractive index

Φ = 38.48⁰

This is approximately 39⁰

Therefore in answer to this question, the angle of internal friction for the soil is nearly 39⁰

Calculate the torque developed by a motor that delivers 200 hp rotation at 3600 rpm. Use the Torque value to determine the diameter of a solid steel shaft with an allowable shear stress of 20,520 psi.

Solution :

Given:

Power, P = 200 hp

              = 110000 lbf ft/s

Speed, N = 3600 rpm

Power , [tex]$P=\frac{2 \pi NT}{60}$[/tex]

∴ Torque, [tex]$T = \frac{60 P}{2 \pi N}$[/tex]

[tex]$T = \frac{60 \times 110000}{2 \pi \times 3600}$[/tex]

T = 291.93 lb -ft

[tex]$T_{allow} = 20,250 \ psi$[/tex] ---- allowable shear stress

Therefore, torque , T = 391.93 lb-ft

                              T   = 291.93 x 12 lb-in

∴ T 3503.16 lb-in

Now from the Torsion formula,

[tex]$\frac{T}{J}=\frac{T_{allow}}{ r}$[/tex]

Here, [tex]$r=\frac{d}{2} ; \ \ \ J=\frac{\pi d^4}{32}$[/tex]   ---- polar moment of inertia.

∴ [tex]$\frac{T}{\frac{\pi d^4}{32}}=\frac{T_{allow}}{ d/2}$[/tex]

[tex]$T_{allow}=\frac{16 T}{\pi d^3}$[/tex]

[tex]$\pi d^3=\frac{16 \times 3503.16}{20520}$[/tex]

[tex]$\pi d^3 = 2.7315$[/tex]

[tex]$d^3 = 0.8699$[/tex]

or [tex]$d= (0.8699)^{1/3}$[/tex]

d = 0.9546 in

Therefore the diameter of the shaft is 0.9546 in.
