Steam enters a turbine from a 2 inch diameter pipe, at 600 psia, 930 F, with a velocity of 620 ft/s. It leaves the turbine at 12 psia with a quality of 1.0, through an outlet duct 1 ft in diameter. Calculate the turbine power output

Explanation:

The model for the turbine is given by the First Law of Thermodynamics:

The turbine power output is:

The volumetric flow is:

The specific volume of steam at inlet is:

State 1 (Superheated Steam)

The mass flow is:

Specific enthalpies at inlet and outlet are, respectively:

State 1 (Superheated Steam)

State 2 (Saturated Vapor)

The turbine power output is:
