Sohar Power Company is one of the leading suppliers of electricity to major industries in Sohar Industrial Port Complex through their steam power plant. In this steam power plant, turbine operates adiabatically with inlet steam at 6600 kPa and 575°C and the exhaust steam enters the condenser at 46°C with a quality of 0.9X. Saturated liquid water leaves the condenser, and is pumped to the boiler.

Sohar Power Company is one of the leading suppliers of electricity to major industries in Sohar
Industrial Port Complex through their steam power plant. In this steam power plant, turbine
operates adiabatically with inlet steam at 6600 kPa and 575°C and the exhaust steam enters the
condenser at 46°C with a quality of 0.9X. Saturated liquid water leaves the condenser, and is
pumped to the boiler.
a. Draw the schematic diagram of power plant indicating its components with conditions
(state) of the fluid.
Calculate the following:
b. Quality of steam from turbine assuming isoentropic expansion
c. Enthalpy of vapor from turbine if the turbine efficiency is 0.7X
d. Amount of heat rejected and work produced from the power plant
e. Thermal efficiency of the cycle and comment whether the cycle efficiency is practically
possible
Note: Neglect pump work and kinetic and potential-energy changes.
