Improve Your Writing
You may need to improve your ability to express yourself in writing.
To some degree, most organisations rely on the accurate transfer of information and that calls for the accurate use of language. When speaking, most people make multiple errors of grammar and vocabulary, and nobody seems to mind. But when you are doing business at work, then the business agreement is usually in the form of a written document; and that document has to be worded properly.
How would you rate your ability to express yourself properly in writing? Are you a good writer or do you lack knowledge of grammar, punctuation, logic and rhetoric?
If you are not as good at writing as you need to be, then study grammar, study punctuation, logic and rhetoric.
Start by buying a copy of a book called 'Rex Barks' by Phyllis Davenport.
This book is the gateway to grammar - and Phyllis is phenomenal.
Explanation:
Atmospheric air at 1 atm has a dry-bulb temperature of 20°C and a wet-bulb temperature of 15°C. Determine the dew point temperature
Answer:
The dew point temperature is 11.65°C
Explanation:
Dew point temperature formula is given as follows;
From the modified Apjohn equation, we have;
[tex]P_v = P'_v -\dfrac{1.8 \times p (t - t')}{2700}[/tex]
Which gives;
The saturation vapor pressure at 15°C = 1.705 kPa
[tex]P'_v[/tex] = 1.705 kPa
p = 101.325 kPa
[tex]P_v[/tex] = 1.705 - 1.8*101.325*(20 - 15)/2700 = 1.36725 kPa
The dew point temperature is the steam saturation temperature at 1.36725 kPa
= 6.9696 + (17.4953 - 6.9696)*(0.0136725 - 0.01)/(0.02 - 0.01) = 10.84°C by approximation calculation from steam tables and 284.8 K = 11.65°C from Wolfram Alpha.

Which type of engineering design uses an already existing design?
A. top-down design
B. spiral design
C. bottom-up design
D.
incremental design
Answer:
The correct option is;
C. Bottom-up design
Explanation:
The bottom-up design is meant for system redesign or re-engineering of an existing design involving component upgrading or legacy systems replacement
The bottom-up design approach is also meant for applications where there is a new interface requirement for the original system in order to determine the functionality of the newly combined systems and also where a novel component is incorporated into the existing design.
The bottom-up approach starts with the analysis of the interoperability of the components to the modules and eventually the analysis of the system requirements.

The evaporative emission monitor or Evaporaive Emission Control System EVAP System monitors enables the Power Control Module of the car to check fuel system leak integrity and the vapor consumption efficiency during engine combustion
It is a requirement of EPA on cars to check the emission of smug forming evaporates from cars
Serious monitor faults can cause the turning on of the check engine lights and the vehicle will not pass OBD II test, but it will not lead to engine shutdown
It runs when the engine is 15 to 85% full and the TP sensor is between 9% and 35%.
Therefore, the correct option is that neither Technician A nor B are correct.
2. What is the charge, expressed in micro coulombs on two equally and similarly charges spheres placed in air with their centres 30 cm apart repelling each other with a force of 120 mgm.
Answer:
q = 0.1086 micro Coulombs
Explanation:
By Coulombs law, we have;
[tex]F =k \times \dfrac{ q_1 \times q_2}{r^2}[/tex]
Where;
F = The electric force = 120 mgm
q₁ and q₂ = Charge
r = The separating distance = 30 cm = 0.3 m
k = 8.9876×10⁹ kg·m³/(s²·C²)
Where, q₁ and q₂, we have;
[tex]F =k \times \dfrac{ q^2}{r^2}[/tex]
Whereby the force is the force of 120 milligram mass, we have;
0.00012 × 9.81 = 000011772 N
[tex]q = \sqrt{ \dfrac{ F\times r^2}{k}}[/tex]
Substituting the values, we have;
[tex]q = \sqrt{ \dfrac{ 000011772 \times (0.3)^2}{8.9876 \times 10^9}} = 1.086 \times 10 ^{-7} \ Coulombs[/tex]
q = 0.1086 micro Coulombs.
a steal bar with 1 in diameter has been subjected to a tensile force of 3 tons find tensile stress in the bar
Answer:
stress = 8,556 Psi. or (stress = 59 Mpa)
Explanation:
stress = force / area
force P = 3 tons (convert to lbs. for units consistency)
1 ton = 2240 lbs.
P = 6,720 lbs.
steel bar Diameter D = 1 in. (convert to d
Area of steel bar = (π * 1²) / 4 = 0.785 in²
therefore, stress = 6720 lbs. / 0.785 in²
stress = 8,556 Psi.
in Mpa ----- 8556 Psi * 0.00689476 MPa/Psi = 59 Mpa

Steam enters an adiabatic turbine at 8 MPa and 500 C with a mass flow rate of 3 kg/s andleaves at 30 kPa.The isentropic efficiency of the turbine is 0.90. Neglecting the kinetic energy change of the steam, determine (a) the tem-perature at the turbine exit and (b) the power output of theturbine
Answer:
(a) The exit temperature = 69.1°C
(b) The power output = 8.3 MW
Explanation:
(a) The enthalpy of steam at 8 MPa and 500°C is given (from online sources) as h₁ = 3399 kJ/kg
The exit temperature = The saturation temperature at 30 kPa = T₄ = 69.096 + 273.15 = 342.246 K
The exit temperature = 69.1°C
(b) The mass flow rate = 3 kg/s
The isentropic efficiency = 0.9 = (h₁ - h₂)/(h₁ - h₂[tex]_s[/tex])
s₁ = 6.727 kJ/kgK
h₂[tex]_s[/tex] = 289.229+ 2335.32* (6.8235 - 6.727 )/6.8235 = 322.26 kJ/kg
Therefore, h₂ = h₁ - (h₁ - h₂[tex]_s[/tex])*0.9
h₂ = 3399 - (3399 - 322.26 )*0.9 = 629.934 kJ/kg
The power output = [tex]\dot m[/tex](h₁ - h₂) = 3 *(3399 - 629.934) = 8307.2 kJ/s =
8.3 MW.

3. An underground copper pipe is used to transport oil under a factory. It is very important that this pipe does not oxidize, so engineers use impressed current cathodic protection. a. Would zinc be an appropriate metal to use for cathodic protection? Why or why not? (4 points) b. Engineers attach a sacrificial anode to the copper pipe. To use impressed current cathodic protection, they must attach a battery between the cathode and anode. Which material should the positive side of the battery be attached to? Explain how you know. (4 points)
Answer:
a) Copper corrosion is prevented by an external current source that provides a condition around the copper that halts the rust through current cathodic protection
Due to the location of the pipeline, an material such as graphite, titanium, or niobium can be used which lasts longer that zinc can be used for longevity of the protection
b) The positive side of the output DC terminals are attached to the anodes such as graphite, while the negative terminals are connected to the copper pipe to be protected
Explanation:
Making the protected metal the cathode will make the metal be the source of electrons into the reaction taking place such that the release of the positive metal ions that results in disintegration takes place at the anode and as such the protected metal made the cathode, to which the negative terminal of the battery is attached is protected.
