3. A ship's steam turbine receives steam at a pressure P1 = 900 psia, T1 = 1000°F, u1 = 1354.5 BTU/lbm, v1 = 0.9273 ft°/lbm and v1 = 100 fps. The steam leaves the turbine at 27 in Hg vacuum with a velocity of 900 fps, T2 = 114°F, u2 = 951.0 BTU/bm, and v2 = 214.0 ftlbm. The turbine entrance is 10 feet above the exit level. Given that 1 hp 2544.5 BTU/hr and 1 BTU = 778.77 ft-lb, find the power produced if the mass flow rate of the steam is 100,000 lbm/hr and the heat loss from the turbine is 50,000 BTU/hr. a. 18,817 hp b. 19,083 hp c. 19,224 hp d. 19,054 hp

Transcribed Image Text:3. A ship's steam turbine receives steam at a pressure P1 = 900 psia, T1 = 1000°F, u1 = 1354.5 BTU/bm,
v1 = 0.9273 ft'/lbm and v1 = 100 fps. The steam leaves the turbine at 27 in Hg vacuum with a velocity of 900
