An insulated steam turbine produces 67,000 hp of power. Steam enters the turbine at 2000 psia and 1000°F, with a velocity of 400 ft/s, through a duct with a cross-sectional area of 0.20 ft2. The steam exits with a velocity of 30 ft/s, at a temperature of 420°F. Determine the exit pressure and, if applicable, the exit quality of the steam.
Given: P1 = 2000 psia; T1 = 1000°F; V1 = 400 ft/s; A1 = 0.20 ft2; T2 = 420oF ; V2 = 30 ft/s; W?=67000 hp=47,365 Btu/s; Steam Assume: Q? = 0 (insulated) Also, for a turbine, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?vPE = 0 What will be an ideal response?
