Considering that a steam turbine has the following properties, what is the isentropic efficiency of the turbine?
Inlet Steam: 600 psig and 1472°F
Turbine Properties: Generator Efficiency = 65% and Power Out = 40 kw
Outlet Steam: 400 psig and 1000°F
Now you have two of these turbines in series, what is the efficiency of the two together?

Combined cycle power plants are common because of their high efficiency and scalability. They typically combine a gas turbine cycle (the Brayton Cycle) with a steam turbine cycle (the Rankine Cycle) [1]. The goal of this project is to determine the operating efficiency and profitability of a realistic combined cycle power plant. The power plant is as follows: 1. A natural gas-fired Brayton cycle with mÛ air,Br = 1.25 kg s−1 . (a) Ambient air at 1 bar and 300...

In a reheat-cycle power plant, steam enters the high-pressure turbine at 5 MPa, 450°C, and expands to 0.5 MPa, after which it is reheated to 450°C. The steam is then expanded through the low-pressure turbine to 7.5 kPa. Liquid water (Vi 0.001 m/kg) leaves the condensor at 30°C, is pumped to 5 MPa, and returned to the steam generator. Each turbine is adiabatic, with an isentropic efficiency of 81.6 % and the pump efficiency is 848 %. If the total...

1) A Rankine cycle with reheat uses 1 kg s-1 of steam though the primary turbine, whose inlet conditions are 400C and 50 Bar. The primary turbine has an isentropic efficiency of 80% and an outlet pressure of 10 Bar. After this turbine, all of the steam is reheated to 400C and passed through a reheat turbine which also has an isentropic efficiency of 80% and whose outlet pressure is 1 bar, which is the condenser pressure. After the condenser,...
