Question 10

Determine the q_h and q_l of a Rankine cycle using steam as the working fluid in which the condenser pressure is 10 kPa. The boiler pressure is 2000 kPa and the steam leaving the boiler is a saturated vapor.

Given: State 1 is the state of the fluid entering the pump, state 2 is state of the fluid entering the boiler, state 3 is state of the fluid entering the turbine and state 4 is the state entering the condenser, and h1 = 191.8 kJ/kg, h2 = 193.8 kJ/kg, h3 = 2799.5 kJ/kg, h4 = 2007.5 kJ/kg

1 point

q_h=1813.7 kJ/kg, q_l=2.0 kJ/kg

q_h=1915.7 kJ/kg, q_l=598.2 kJ/kg

**q_h=2605.7 kJ/kg, q_l=1815.7 kJ/kg**
