A ship’s steam turbine receives steam at a pressure P1 = 900 psia, T1 = 1000°F, u1 = 1354.5 BTU/lbm, 1 = 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 2 = 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 ship’s steam turbine receives steam at a pressure P1 = 900 psia, T1 = 1000°F, u1 = 1354.5 BTU/lbm, 1 = 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 2 = 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.

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 ft³/lbm and v₁ = 100 fps. The steam leaves the turbine at 27 in Hg vacuum with a velocity of
fps, T₂ = 114°F, u₂ = 951.0 BTU/lbm, and v₂ = 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.
