Example contains a situation involving a large steam turbine. Using the data provided there and assuming the values of all the remaining variables are constant, plot the turbine's heat loss as a function of

a. The steam flow rate.

b. The surface temperature of the turbine.

c. The ground state temperature (note that changing T0 changes the af values).

Example :
A large uninsulated steam turbine receives superheated steam at 18.0 kg/s, 500.°C, and 3.00 MPa and exhausts it to 0.0100 MPa with a quality of 96.0%.

If the turbine is assumed to be internally reversible, determine the rate of heat loss from the surface of the turbine if the power output is 20.0 × 103 kW.

The surface temperature of the turbine is uniform at 350.°C, and the local environment (ground state) is taken to be saturated liquid water at T0 = 20.0°C. Neglect all flow stream kinetic and potential energies in this problem.
