A steady state condenser pipe rejects heat as H2O cools from a saturated vapor to saturated liquid at 101.3 KPa. If the heat rejection is 5MW:
a. Determine the mass flowerate of H2O
b. What should the area of pipe be if the velocity of H2O should never surpass 2 m/s?
c. What is the maximum power output from a plant utilizing this condenser if the plant receives heat from a 600K source?
