Question

A rankin cycle uses water as a working fluid which circulates at a rate of 80kg/s. The boiler pressure is 6MPa and exit temperature is 700 degrees celcius. The condenser pressure is 10KPa. The water leaves the condenser as a saturated liquid. The boiler receives heat from a hot source at 1400K and the condenser rejects heat to atmosphere at 25 degrees celcius.

a) power from turbine if process in turbine is isentropic

b) heat input in boiler

c)power needed for the pump

d)calculate the term [h-T0S]inlet and [h-T0S]exit for turbine where T0=298K

Explanation / Answer

b) heat input in boiler
