A power plant uses a gas-turbine, operation can be modeled using a simple Brayton cycle. Using air as the working fluid, the power plant can produce 30 MW of power. The pressure at the end of the compression process is 9 times larger than the pressure just before the compression process. The isentropic efficiency of the turbine and compressor or 87% and 82% respectively. If the minimum temperature during the cycle is T = 315 K, and the maximum temperature in the cycle is T = 950 K,determine the mass flow rate of the working fluid during the cycle. Assume that specific heats are a function of temperature.
