A Rankine cycle steam plant operates between the pressures of 15 MPA and 6 kPa. Steam exiting the boiler is 550 degrees C. Water leaving the condenser is saturated. The turbine efficiency is 82% and the pump efficiency is 78%. The steam flow rate is 1,000,000 kg/hr.
a) draw cycles on t-s and h-s diagrams
b) determine all required enthalpies.
c) determine turbine power
d) determine pump power using enthalpies
e) determine pump power using v( delta P)
f) determine thermal efficiency
g) the steam in the condenser is cooled with sea water from a nearby body of water. If cooling water to the condenser is limited to 7 degrees C temp rise, determine the flow of cooling water.
