An insulated compressor uses 25 hp of power to compress air from 14.7 psia to 80 psia. The air enters at 75oF, and the volumetric flow rate at the inlet is 2.50 ft3/s. Determine the temperature of the air exiting the compressor.
Given: P1 = 14.7 psia; T1 = 75oF; P2 = 80 psia; W?= ?25 hp=?17.67 Btu/s; V?= 2.50 ft3/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
