Need help understanding how to tackle this textbook problem: Steam turbine operates under steady flow conditions with 20 kg/s of steam entering at 1.7 MPa and 350°C that leaves at 30°C with a quality equal to 0.96. The turbine has been in operation for two years and the thermal insulation has degraded, thus it is no longer adiabatic, and a heat loss to the surroundings is estimated to be equal to 5% of the power produced. a. Create a schematic for the turbine and include the boundary that you would use to determine the power produced by the turbine along with all the mass and energy interactions between the system and the surroundings.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

b. On a P-v diagram represent the process for the steam in the turbine with respect to the saturation lines and other distinct property lines with their value.
c. Starting with the general form for the mass and energy conservation expressions for a control volume, compute the power produced by the turbine and the rate of heat loss to the surroundings.
d. List the assumptions you used in part (c) with their adequate justification.
