The mass rate of flow into a steam turbine is 4500 kg/h and the heat transfer from the turbine is 8.8 kW. The following data are known for the steam entering and leaving the turbine.
Pressure 20 bar 1 bar
Temperature 420 C
Velocity 60 m/s 150 m/s
Elevation above datum 5 m 3 m

Please see the attachment for a solution.
The useful power can be determined by applying the equation of energy:
steam (water) mass flow rate (kg/s)
inlet specific static enthalpy (and similarly for the outlet) (kJ/kg)
The output power of a steam turbine is determined based on the mass rate of flow and heat transfer.
