A ship’s steam turbine receives steam at a pressure of 700 [psia] and a velocity of 100 [ft/s]. The steam leaves the turbine at 27 in Hg vacuum with a velocity of 900 [ft/s]. The turbine entrance is 5 [ft] above the exit level. Find the power produced in [Btu/hr] if the mass flow rate of the steam is 500 [lb/hr] and the heat loss from the turbine is 5000 [Btu/hr]. The steam has the following properties:

Question
A ship’s steam turbine receives steam at a pressure of 700 [psia] and a velocity of 100 [ft/s]. The steam leaves the
turbine at 27 in Hg vacuum with a velocity of 900 [ft/s]. The turbine entrance is 5 [ft] above the exit level. Find the
power produced in [Btu/hr] if the mass flow rate of the steam is 500 [lb/hr] and the heat loss from the turbine is 5000 [Btu/hr]. The steam has the following properties:
