A two-stage compression refrigeration system with an adiabatic liquid- vapor separation unit uses refrigerant-134a as working fluid. The system operates the evaporator at -32°C, the condenser at 1.4 MPa, and the separator at 8.9°C. The refrigerant is circulated through the condenser at a rate of 2 kg/s. Given that the refrigerant is saturated liquid at the inlet of each expansion valve and saturated vapor at the inlet of each compressor, and the compressors are isentropic; ) show the process on a T-s diagram; (ii) calculate the rate of cooling produced by evaporator; and (iii) determine the total power requirement for this system

Question 4 a) Each cylinder in a four-cylinder car engine has a bore diameter of 63.53 mm and the stroke for each piston is 175.00 mm. Calculate the cubic capacity of the engine in cm? and calculate the clearance volume per cylinder for a compression ratio, r, of 6.25. b) The bore diameter of each cylinder in a six-cylinder four-stroke internal combustion engine is 32 mm and the stroke of each piston is 125 mm. During testing., the engine runs at 1450 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 2.90 cm and a diagram length of 0.85 cm. The pressure scale on the indicator diagram is set to 165 kN/m per cm.
