Consider a steam power plant that operates a reheat Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 10 MPa and 500°C and the low-pressure turbine at 1.4 MPa and 500°C. Steam leaves the condenser as a saturated liquid at a pressure of 10 kPa. Assume both turbine and compressor are isentropic. Determine the thermal efficiency of the cycle. Use steam tables. The thermal efficiency of the cycle is 100 %.

Expert Solution
Step 1: Given

The net power output is P equals 80 space M W.

The steam enters the high pressure turbine at 10 space M P a comma space 500 degree C.

The steam enters the low pressure turbine at 1.4 space M P a comma space 500 degree C

The pressure of the condenser is 10 space k P a.
