An insulated compressor uses 35.0 kW of power to compress air from 100 kPa to 1400 kPa. The air enters at 25oC, and the mass flow rate is 0.092 kg/s. Determine the temperature of the air exiting the compressor.
Given: P1 = 100 kPa; T1 = 25°C; P2 = 1400 kPa;W?= ?35.0 kW; m?= 0.092 kg/s; 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?
