A steam power plant uses an ideal Rankine cycle. Superheated vapor enters the turbine at 8 MPa, 480C. The condenser pressure is 8 kPa. The net power output of the power plant is 100 MW. Find;
a) Temperature, pressure, specific volume, internal energy for each state in the cycle.
b) Sketch a detailed T-s diagram.
c) The rate of heat transfer in the generator, in kW.
d) The thermal efficiency
e) The mass flow rate of the condenser cooling water, in kg/hr if the cooling water enters the condenser at 15C and exits at 35C with negligible pressure change.
A water tank consists of a cylindrical part of radius r and height h and a hemispherical top. The tank is to be constructed to hold 600 m3 when led. The surface area of the cylindrical part is 2 rh, and its volume is r2 h. The surface area of the hem..
five kilograms of water initially at 4000 kpa 200 degrres are contained in a piston-cylinder device. a variable force
Heat transfer to air takes place partly at constant volume and partly at constant pressure, and it amounts to 1520.4 kJ/kg. Determine (a) the fraction of heat transferred at constant volume and (b) the thermal efficiency of the cycle.
