Question

Air enters the compressor of a cold air-standard Brayton cycle with regeneration at 100 kPa, 300 K, with a mass flow rate of 6 kg/s. The compressor pressure ratio is 10, and the turbine inlet temperature is 1400 K. The turbine and compressor each have isentropic efficiencies of 80% and the regenerator effectiveness is 80%. For k = 1.4, calculate (a) the thermal efficiency of the cycle. (b) the back work ratio. (c) the net power developed, in kW.

Step 1

First, we need to find the temperature and pressure at each state (1, 2, 3, and 4). State 1: Given, $T_1 = 300\,\text{K}$ and $P_1 = 100\,\text{kPa}$. State 2: Using the isentropic relation and the compressor pressure ratio, we can find the ideal temperature at Show more…
