A ship’s steam turbine receives steam at a pressure P1 = 900 psia, T1 = 1000°F, u1 = 5 BTU/lbm, u1 = 0.9273 ft3/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/lbm, and u2 = 214.0 ft3/lbm. 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 hpb.19,083 hpc.19,224 hpd.19,054 hp

Question

A ship’s steam turbine receives steam at a pressure P1 = 900 psia, T1 = 1000°F, u1 = 5 BTU/lbm, u1 = 0.9273 ft³/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/lbm, and u2 = 214.0 ft³/lbm. 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.
