Answer to Question #338667 in Chemical Engineering for Mohit

Question

4.32 (a) Nitrogen gas (C P =30 kJ/ kmol K) at 1 bar and 300 K is to be compressed to 10 bar and

450 K at a rate of 5000 kg/h. Cooling water (C_{P} = 4.1868kJ / k * gK) enters the compressor at 300 K at the rate of 7500 kg/h and leaves at 320 K. Determine the power required by the compressor. (b) For the same conditions of nitrogen as in the previous part, determine the minimum power required by the compressor. The rate of circulation and the inlet temperature of cooling water

remain the same as above.
