Air at T₁ = 32°C, p₁ = 1 bar, 50% relative humidity enters an insulated chamber operating at steady state with a mass flow rate of 3 kg/min and mixes with a saturated moist air stream entering at T₂ = 7°C, p₂ = 1 bar. A single mixed stream exits at T₃ = 17°C, p₃ = 1 bar. Neglect kinetic and potential energy effects

A) Determine mass flow rate of the moist air entering at state 2, in kg/min. (Answer was 4.5 kg/min)

B) Determine the relative humidity of the exiting stream. (Answer was 79.6%)

C) Determine the rate of entropy production, in kJ/min.K.

Need part C. Thank you

Use water as the working fluid ,apply Rankine power cycle with reheat . The first stage turbine inlet conditions are 15MPa and 600 C. All the turbines are known to have isentropic efficiency of 95%, however the pump is assumed as an isentropic pump. If the maximum temperature is kept at 500 C and the condenser pressure is 5 kPa, by constructing a suitable plot, show that having more than 2 reheat stages is not practical. (Hint: Take at least three reheat pressures between 3 to 13 MPa)

hi please provide the graph and calculation. design an appropriate plot, show that it's not practical to have more than two reheat stages (take at least three reheat pressures between 2 to 12 MPa).reheated Rankine power cycle uses water as working fluid. The first stage turbine 's inlet conditions are 14MPa, and 600oC.All turbines are known as isentropic 85 percent efficiency,the pump is assumed as an isentropic pump.If the maximum temperature is maintained at 600oC and the condenser pressure is 6 kPa

Which of the following modifications would REDUCE the likelihood of cavitation in a pump and piping system?

a) raising the pump

b) increasing the flow rate

c) lowering the position of the pump in the system

d) raising the temperature of the pumped fluid

e) lowering the inlet piping to the pump, while keeping the pump in the same position

TRUE OR FALSE? In pipe flow, if the Reynolds number is very large, then the friction factor depends only on the non dimensional pipe roughness.

The drag force on a large ball that weighs 200 g in free flight is given by FD = 2*10 V , where FD is in Newtons and V is in meters per second. If the ball is dropped from rest 300 m above the ground, determine the speed at which it hits the ground. What percentage of the terminal speed is the result?

An ideal vapor-compression refrigeration cycle is modified to include a counterflow heat exchanger, as shown in the figure below. Ammonia leaves the evaporator as saturated vapor at 1 bar and is heated at constant pressure to 5°C before entering the compressor. Following isentropic compression to 18 bar, the refrigerant passes through the condenser, exiting at 40°C, 18 bar. The liquid then passes through the heat exchanger, entering the expansion valve at 18 bar.

If the mass flow rate of refrigerant is 16 kg/min, determine:

(a) the refrigeration capacity, in tons of refrigeration.

(b) the compressor power input, in kW.

(c) the coefficient of performance.

(d) the rate of entropy production in the compressor, in kW/K.

(e) the rate of exergy destruction in the compressor, in kW.

Let T₀ = 20°C

A vapor-compression refrigeration system for a household refrigerator has a refrigerating capacity of 1650 Btu/h. Refrigerant enters the evaporator at -15°F and exits at 20°F. The isentropic compressor efficiency is 75%. The refrigerant condenses at 125°F and exits the condenser subcooled at 100°F. There are no significant pressure drops in the flows through the evaporator and condenser.


For Refrigerant 134a as the working fluid, determine:

(a) the evaporator and condenser pressures, each in lbf/in.²

(b) the mass flow rate of refrigerant, in lb/min.

(c) the compressor power input, in horsepower.

(d) the coefficient of performance.
