An ideal gas at a fl ow rate of 10.0 m3/min enters a compressor at 25°C and 1 bar. It leaves at 1 MPa. During this process, heat is dissipated to the surroundings at a rate of 2100 W. You may take the surroundings to be at a constant temperature of 25°C. The heat capacity of the ideal gas is given by:

where T is in [K]. Answer the following questions:

(a) Assuming this process is reversible, calculate the temperature at the compressor outlet.

(b) Calculate the minimum power required to compress the gas.

(c) If the compressor effi ciency is 70%, calculate the actual power needed.

(d) Calculate the actual fi nal temperature.
