Required information Air at 1(atm) and 35°C is compressed in a staged reciprocating compressor (with intercooling) to a final pressi of 50(atm). For each stage, the inlet gas temperature is 35°C and the maximum allowable outlet temperature Mechanical power is the same for all stages, and isentropic efficiency is 70% for each stage. The volumetric S is 0.5 m³.s1 at the inlet to the first stage. Assume air is an ideal gas with Cp= (7/2)R. Take R= 82.06 cm³ (atm = 8.314 J-mol-1.K-1. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What is the mechanical power requirement per stage? The mechanical power requirement per stage is 66.1744 kW.
