A gas turbine (can assume an ideal Brayton cycle) has a pressure ratio of 10. It is connected to an electric generator with an efficiency of 95% which produces 300kW of electricity. The gas turbine burns natural gas with a heating value of 100,000 btu/therm. The waste heat from the gas turbine is used by an absorption chiller with a COP of 0.8. What would you estimate the cooling capacity of the absorption chiller to be?
