An insulated steam turbine receives steam at 8.0 MPa, 400°C, and a mass flow rate of 35 kg/s. For a steam exit pressure of 20 kPa, using your turbine model, plot the power produced for
(a) exit qualities ranging from 0.85 to 1.0 and (b) exit steam temperatures ranging from 65°C to 200°C. Given: P1 = 8.0 MPa; T1 = 400°C; m?=35 kg/s; P2 = 20 kPa; Steam State 1 is the inlet, state 2 is the outlet. Assume: Q? = 0 (insulated) Also, for a turbine, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?KE = ?PE = 0
