Q1: Consider a reheat regenerative vapour power cycle with a feed-water heat
steam enter the first turbine at 15 MPa, 600°C and expands to 2 MPa. Then the ste
reheated to 600°C at the same pressure. The steam for feed-water heater is extracted
the low-pressure turbine at the pressure of 0.5 MPa and the remaining steam is furt
expanded to a condenser pressure of 10 kPa. The working fluid experiences n
irreversibilities, passes through turbines, pumps, boiler, reheater condenser. Determine:
(a) The fraction of steam extracted from the turbine for feed-water heater,
(b) Thermal efficiency of the cycle,
(c) Mass flow rate of steam in kg/h, if cycle produces 210 MW.
