# A turbine salesman makes the following claim

A turbine salesman makes the following claim for one of his products: Steam enters a steady-flow adiabatic turbine at 4 MPa, 600 °C with negligible velocity and exhausts at 200 kPa with a velocity of 180 m/s. The flow rate is 2.2 kg/s and the turbine power is 2 MW.

a. If the turbine operated as described by the salesman, what would the temperature of the exhaust steam be?

b. Could the salesman's claim be valid? Explain and justify your response. (Hint: look at the Clausius Inequality.)

#### Solution Preview

Please see the attached file.

a. Apply energy balance for a turbine:

but V1 = 0 and V2 = 180 (m/s)

From steam table, h1 = 3674.4 (kJ/kg), s1 = ...
