A Brayton cycle uses a regenerator between the compressor and combustor to reduce the heat needed to be added through the combustor. Air enters the compressor at 100 kPa and 10°C and is compressed to 1000 kPa. The air then passes through a regenerator with a regenerator effectiveness of 0.80. The air expands through the turbine to a pressure of 100 kPa. The mass flow rate of the air is 20 kg/s. The isentropic efficiency of the turbine is 0.80, and the isentropic efficiency of the compressor is 0.75. Consider the specific heats of the air to be variable. Plot the net power produced by the cycle, the heat input, and the thermal efficiency of the cycle for turbine inlet temperatures ranging between 1000 K and 1400 K.
