As the refrigerant as shown in the figure, R134a fluid is used in a commercial refrigerator. The refrigerant leaves the evaporator at a temperature of -33.5°C (239.65 K) and a pressure of 60 kPa. It is then compressed to a pressure of 1.2 MPa and a temperature of 64°C (337.15 K). In the water-cooled condenser, the refrigerant is cooled to 41°C (314.15 K). Water enters the condenser at 18°C and leaves at 26°C. In this context; *Calculate the degree of dryness (quality) of the refrigerant at the evaporator inlet [%].

It is desired to heat cold water at a pressure 500 kPa from 5 oC to 50 oC at a rate of 0.1 kg/s in a thin-walled copper tube by condensing waste process steam at 300 kPag on the outside of the tube. At 400 kPa abs, T sat = 143 oC. Determine the log mean temperature difference.
A commercial airliner is flying at an altitude where the temperature and pressure of the air are -50°C and 26.5 kPa. An engine-driven compressor will take this air at T= -50°C, P₁ = 26.5 kPa and compress it to P₂ = P₂ = 85.0 kPa to pressurize the cabin. The air will be very hot when it exits the compressor, so a heat exchanger will be used to cool the air to T, = 20°C before it enters the cabin. Cold air at T₁ = -50°C will be used in the heat exchanger to cool the cabin air, and this air will exit the heat exchanger at T = 20°C (this air will be used to heat the cargo bay). The mass flow rate of the air delivered to the cabin is 0.80 kg/s and the compressor efficiency is 75%. Model the air as an ideal gas having constant specific heat, using 300 K values from Cengel's tables posted on Canvas. a) Find the actual temperature of the air exiting the compressor and the power input to the compressor (answers: 67.6°C and 94.5 kW). b) Find the rate of heat transfer in the heat exchanger and…

If saturated liquid steam at 850 kPa is throttled to 120 kPa, what is the quality of the resulting steam?
1. Steam at a pressure of 2MPA and temperature 300°C is passed at a constant rate into a desuperheater unit. The desuperheater is accomplished by continuously spraying water at 95 °C onto incoming superheated steam. The amount of water injected is so regulated that both the water and superheated steam finally change into dry steam at 2 MPa. If the resulting mixture of dry saturated steam leaves the desuperheater at 2MPA and the rate of I kg/s, find the mass of superheated steam used per hour and the mass of water to be injected per hour. Fond also the diameter of the pipe through which the superheated steam flows to the superheater if the speed of the steam through the pipe is not to exceed 25m/s..
