Question
Transcribed Image Text:As shown in figure 4, a combined gas turbine power plant
operates with state 5 being an air compressor inlet at a
temperature of 300 K and state 3 being a steam turbine inlet
with a temperature of 1500 K. The pressure ratio of the gas-
turbine cycle is 16. The isentropic efficiency of the
compressor and turbine are 80% and 85% respectively. Air
flow in the system with mass flow rate of 10 kg/s and the
with turbine outlet temperature of 400 °C. The heat
exchanger operates at 12 MPa and the combustion gas exit
at 420 K. Steam leaves the condenser at 19.947 kPa. If the
pump efficiency is 90%, Complete the table below: All to one
decimal place except the Pr, 's and x to 4 decimal places.
If there are no numbers to write on decimal, replace the
value with zero. For example, 6.56 to 4 decimal places may
be written as 6.5600 and 898.8878 may be entered as
899.0
