A closed ideal gas turbine plant operates between temperature limits of 8000 C and 300C and produces a power of 100 kW. The plant is designed such that there is no need for a regenerator. A fuel of calorific value 45000 kJ/kg is used. Calculate the mass flow rate of air through the plant and the rate of fuel consumption. (Assume Cp = 1 kJ/kg K and the ratio of specific heats = 1.4)
