    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.

    Inlet Exit
    Pressure 20 bar 1 bar
    Temperature 420 C
    Quality 100%
    Velocity 60 m/s 150 m/s
    Elevation above datum 5 m 3 m

    Determine the output power of the turbine.

    Solution:

    The useful power can be determined by applying the equation of energy:
    (1)
    where
    steam (water) mass flow rate (kg/s)

    inlet specific static enthalpy (and similarly for the outlet) (kJ/kg)
    ...

    Solution Summary

    The output power of a steam turbine is determined based on the mass rate of flow and heat transfer.
