Consider a simple Brayton cycle that uses air as the working fluid to operate a gas-turbine power plant between the pressure limits of 100kPa and 900kPa. Air enters the compressor at 298K and leaves at 610K at a mass flow rate of 1200kg/min. The maximum cycle temperature is 1380K. The net power output from the cycle is measured experimentally to be 55 MW. Assuming constant properties (C_{v},C_{p}, R, and k) for air at 300K:

- a) Sketch a T-s diagram for the cycle
- b) Determine the isentropic efficiency of the turbine
- c) Determine the thermal efficiency

Step 1

Given information:

Step 2

(a)Draw the T-S diagram for the cycle

Step 3

From the process 3-4 we ...
