An uninsulated steam turbine receives steam at 10.0 MPa, 600°C, and exhausts steam at 10 kPa, 100°C. The mass flow rate of the steam is 45 kg/s. Using your turbine model, plot the power produced by the turbine for heat transfer rates for the turbine ranging from 0 MW to -10.0 MW.
Given: P1 = 10.0 MPa; T1 = 600°C; T2 = 100°C; m?=45 kg/s; P2 = 10 kPa; Steam State 1 is the inlet, state 2 is the outlet. Assume: For a turbine, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?KE = ?PE = 0 What will be an ideal response?
