An insulated air compressor receives 0.65 lbm/s of air at 14.7 psia and 70oF. The air is compressed to 125 psia. For exit temperatures ranging from 550oF to 750oF, use your compressor model to plot the power required by the compressor. (The higher the exit temperature, the less efficient the compressor is.)
Given: P1 = 14.7 psia; T1 = 70oF; m?= 0.65 lbm/s; P2 = 125 psia; Air (Take State 1 as the inlet, State 2 as the outlet.) Assume: Q?=0 (insulated). For a compressor, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?KE = ?PE = 0 What will be an ideal response?
