A steam power generation plant produces 200mw of power. Steam leaves the dealer at 150 bar and 650°c. After expansion through the first stage turbine to a pressure of 40 bar, 15% of the steam is extracted to feed the water heater. The remaining steam is heated to 650°c then expanded to a condenser pressure of 0.04 bar through a second turbine stag. It is assumed that the actual cycle will have an efficiency of 70% and the generator mechanical and electrical efficiency is 95%. Calculate the mass flow rate of steam in kg/hr. The steam rate.
