An adiabatic pump receives liquid water at 25°C and 100 kPa. The water exits at 30.0 MPa and 40.0°C. Using your pump model, plot the power required for this pumping operation for entering volumetric flow rates ranging from 0.001 m3/s to 1.0 m3/s.
Given: P1 = 100 kPa; T1 = 25°C; P2 = 30,000 kPa; T2 = 40°C Water (Take State 1 as the inlet, State 2 as the outlet.) Assume: Q?=0 (adiabatic). For a compressor, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?KE = ?PE = 0 What will be an ideal response?
