Mechanical Engineering

Consider a simple ideal Rankine cycle which uses water as theworking fluid. The net power of power plant is 220-MW. At theturbine inlet, steam is at 9 MPa and 560°C. The condenser pressureis 20 kPa. Determine the following values.  

The temperature at the pump inlet.

°CThe specific enthalpy at the pump inlet.

kJ/kgThe specific volume at the pump inlet.

m3/kgThe pump work.

kJ/kgThe temperature at pump exit.

°CThe specific entropy at turbine inlet.

kJ/kg·KThe quality of steam at turbine exit.

The temperature of steam at turbine exit:

°C. Now using calculated T and s values draw a T-s diagram tocompare with the one in notes or textbook. You may use theplot_TS_water function. The thermal efficiency of the cycle.

%

The mass flow rate of the steam.
