Steam enters a turbine operating at steady state with a specific enthalpy of 1407.6 Btu/lb and expands to the turbine exit where the specific enthalpy is 1236.4 Btu/lb . The mass flow rate is 5 lb/s. During this process, heat transfer to the surroundings occurs at a rate of 40 Btu/s


Neglecting kinetic and potential energy effects, the power developed by the turbine is

Option A: 816 Btu/s

Option B: 896 Btu/s

Option C: 656 Btu/s

Option D: 74.2 Btu/s
