Answer the following statement true (T) or false (F)
An uninsulated turbine receives superheated steam at 1000 psia, and the steam exits as a saturated vapor at 60 psia. There is a heat loss of 900 Btu/s from the turbine. The mass flow rate of the steam is 55 lbm/s. Using your turbine model, plot the power produced by the turbine for inlet temperatures ranging from 600oF to 950oF.
Given: P1 = 1000 psia; x2 = 1.0 (saturated vapor); m?=55 lbm/s; P2 = 60 psia; Q?=?900Btus; 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?
