An ideal brayton cycle gas turbine engine has a pressure ratio of 12. the inlet air is taken at 300 k, 100 kpa. the heat released by the fuel is 1000 kj/kg. the gas turbine produces 300 kw of net power. the dead state can be taken at inlet conditions. air is to be used and treated as an ideal gas. cold air analysis.

find:
a) the combustion temperature, k.
b) the engine air mass flow rate, kg/s.
c) the cycle thermal efficiency.
d) the back-work ratio.
e) what is the energy rate (kwh) in the turbine exhaust.
