At steady-state, an ideal gas enters a cempressor with a mass flow rate of 10.0 [mol/s]. Thei pressure is 1.00 bar and the inlet temperature is 25.0*C. The gas exits at 25.0 bar and 65.0°C. The ideal gas heat capacity is given by: nlet 4. cnm = 3.60 + 0.500 x 10-3T Where T is in [K]. a) Assuming the compressor is adiabatic, calculate the power (in kW) required. b) in the real process, there is a finite amount of heat transfer. If the compressor operates between the same initial state and final state as in Part A, will the actual power required be greater than, equal to, or less than that calculated in Part A? Explain.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
