Question

Determine the Q_h and Q_l of a Rankine cycle using steam as the working fluid in which the condenser pressure is 10kPa. The boiler pressure is 2000 kPa and the steam leaving the boiler is a saturated vapor. Given: State 1 is fluid going into pump, state 2 is fluid going into boiler, state 3 is fluid going into turbine and state 4 is going into condenser. h1=191.8 kJ/kg, h2=193.8kJ/kg, h3=2799.5kJ/kg, h4=2007.5kJ/kg Q_h=1815.7, Q_l=598.2kJ/kg Q_h=1813.7kJ/kg, Q_l=2.0kJ/kg Q_h=2605.7kJ/kg, Q_l=1815.7kJ/kg Determine the Q_h and Q_l of a Rankine cycle using steam as the working fluid in which the condenser pressure is 10kPa. The boiler pressure is 2000 kPa and the steam leaving the boiler is a saturated vapor. Given: State 1 is fluid going into pump, state 2 is fluid going into boiler, state 3 is fluid going into turbine and state 4 is going into condenser. h1=191.8 kJ/kg, h2=193.8kJ/kg, h3=2799.5kJ/kg, h4=2007.5kJ/kg Q_h=1815.7, Q_l=598.2kJ/kg Q_h=1813.7kJ/kg, Q_l=2.0kJ/kg Q_h=2605.7kJ/kg, Q_l=1815.7kJ/kg Q_h=1815.7, Q_l=598.2kJ/kg Q_h=1813.7kJ/kg, Q_l=2.0kJ/kg Q_h=2605.7kJ/kg, Q_l=1815.7kJ/kg

Explanation / Answer

Q_h=h3-h2=2799.5-193.8=2605.7 Kj/kg

Q-i=h4-h1=2007.5-191.8=1815.7 Kj/kg
