A gas turbine power plant operating on a Brayton cycle takes in atmospheric air at 12°C. The temperature of the air rises by 160°C over the compressor, and by a further 747°C over the combustion chamber. If the heating value of the fuel burned in the turbine is 42 MJ/kg, calculate the rate in kg/s at which fuel must be burned for each MW of output from the power plant. Give your answer to three decimal places. Take the specific heat capacity cp of air to be 1.005 kJ/(kg K), and the ratio of specific heats k to be 1.4. You may also assume that changes in the properties of the air due to the addition and combustion of fuel are negligible.
