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
Answers: 1

- Heat transfer rate, measured in BTU per second.
- Power developed by the turbine, measured in BTU per second. 
- Mass flow rate, measured in pounds per second. 
, 
- Specific enthalpies at inlet and outlet, measured in BTU per pound. 
, 
, 
and 
, then the power developed by the turbine is:
