1.1875 has the IEEE 754 encoding of 0xC2F00000. This is represented as 1 sign bit, 1000 0000 (binary), or 128 biassed exponent (decimal.
The sign bit is set to 0 for positive numbers and 1 for negative numbers when encoding a number in IEEE 754 format. The bias, which for single-precision values is 127, is subtracted to get the value of the exponent field, which is then multiplied by the power of 2 that should be used to multiply the mantissa. A binary fraction is then used to represent the mantissa. To encode -1.1875, for instance, the sign bit would be set to 1, the exponent field would be set to 128-127=1, and the mantissa would be set to 1110 0010 1111 0000 0000 0000 0000 0000.)

The force exerted on the clothes during the spin cycle of an automatic washing machine is________
During the washing machine's spin cycle, the centrifugal force can be used to throw the water molecules on the clothes radially outwards because it acts along the radius.
How does a washing machine use centrifugal force?Your clothes are pushed toward the edges of the washing machine, which are frequently punctured with tiny holes, by this centrifugal force. After being pressed against the machine's sides, the force removes the water from your clothes.
What is the force that you apply to a machine?The input force or effort force is the force you apply to the machine. The term "output force" or "resistance force" refers to the force that the machine produces. By increasing either force or distance or changing the direction of force, a machine makes work simpler.

b) A vapor compression refrigerator uses methyl chloride and works in the pressure range of 1.19 bar and 5.67 bar. At the beginning of compression, the refrigerant is 0.96 dry and the end of isentropic compression its temperature is 55 °c. The refrigerant liquid leaving the condenser is saturated.
If the mass flow of refrigerant is 1.8 kg/min.
The calculation of the coefficient of performance, the rise in temperature of condenser cooling water, and the ice produced in the evaporator can be done using the energy balance equations for the refrigeration cycle.
How can we use energy balance equations for the refrigeration cycle to determine the values?(i) Co-efficient of Performance (COP):
COP is defined as the ratio of the cooling capacity to the power required for refrigeration.
COP = Cooling capacity / Power required for refrigeration
The cooling capacity can be determined using the energy balance on the evaporator, which states that the heat absorbed by the refrigerant in the evaporator is equal to the heat rejected by the condenser.
Cooling capacity = m_ref * (h2 - h1)
where
m_ref = 1.8 kg/min, mass flow rate of refrigerant
h2 = enthalpy of refrigerant at the end of isentropic compression, 55°C
h1 = enthalpy of refrigerant at the beginning of the compression, 0.96 dry
The power required for refrigeration can be calculated as the work done on the refrigerant during the isentropic compression process.
Power required for refrigeration = m_ref * (h2 - h1)
Now we can calculate the COP using the above equations.
(ii) Rise in temperature of condenser cooling water:
The rise in temperature of condenser cooling water can be calculated using the energy balance on the condenser. The heat rejected by the refrigerant in the condenser is equal to the heat absorbed by the condenser cooling water.
Q_rejected = m_cw * Cp * (T_out - T_in)
where
m_cw = 16 kg/min, mass flow rate of condenser cooling water
Cp = 4.187 kJ/kg, specific heat of water
T_out = Final temperature of cooling water
T_in = Initial temperature of cooling water
We can solve for the rise in temperature (T_out - T_in) using the above equation.
(iii) Ice produced in the evaporator:
The ice produced in the evaporator can be calculated using the energy balance on the evaporator and the latent heat of fusion of ice.
Q_absorbed = m_ice * hf
where
m_ice = Mass of ice produced
hf = 336 kJ/kg, specific enthalpy of fusion of ice
We can solve for the mass of ice produced (m_ice) using the above equation.
Note: The above calculations require the enthalpies of the refrigerant at various states, which can be obtained from thermodynamic tables.

consider a wall refrigerator unit (home ac unit) which is used to cool down a home during the summer. its coefficient of performance in cooling mode is 4.06 if the refrigerator consumes 500 w of electrical power, at what rate does it remove heat from the home?
A refrigerator with a performance coefficient of K=5 removes heat from the cooling compartment at a rate of 250 J/cycle.
Therefore, the relationship between a heat engine's efficiency and a refrigerator's co-efficient of performance. The usable heating or cooling delivered to work (energy) required ratio, also known as the coefficient of performance, or COP, of a heat pump, refrigerator, or air conditioning system. Higher efficiency, less energy (power) usage, and thus reduced operational costs are all related to higher COPs.

If the liquid volume v is constant, the dynamic model for this process is:
A continuous-flow reactor is used to conduct an isothermal reaction. 10 dm3/h is the volumetric flow rate that is arriving at v 0.
The initial mass of the tank's liquid water is 2000 lb. The mass of the water in the tank is equal to m. hot water mass flow rate = m1 = 0.8 lb/s. cold water mass flow rate = m2 = 1.2 lb/s. m3 = 2.5 lb/s is the mass flow rate of liquid water via a single outlet pipe. Time = t = 1 hour. So, the following formula is used to get the tank's final water mass: The equation that follows is derived from the mass rate balancing equation.

Interface design is a technique for addressing problems driven by the desired function, destination IP address, materials, cost, and sustainability.
Interaction design (IxD), a method for developing interactive products and services, involves analyzing both the final product and the way consumers will interact with it. Consequently, careful evaluation of the needs, limitations, settings, etc. of the users enables designers to change the output to meet particular needs. As you may already be aware, interface design and UX design share a lot of similarities.
