An insulated pump receives liquid engine oil (??= 55 lbm/ft3, c = 0.442 Btu/lbm-R) at 75oF and 15 psia, and exhausts the oil at 3000 psia and 140oF. The mass flow rate of the oil is 1.2 lbm/s. Determine the power required by the pump

Given: P1 = 15 psia; T1 = 75oF; m?= 1.2 lbm/s; P2 = 3000 psia; T2 = 140oF Water (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?
