An ideal cold-air standard closed Brayton cycle operates with a compressor pressure ratio of 14. The minimum and maximum temperatures are 520 °R and 3000 °R, respectively. The rate of heat addition is 3.4 x 109 BTU/h. Evaluating specific heats at 520 °R: a. Draw the process on a T-s diagram b. What is the thermal efficiency of the cycle? c. What is the mass flow rate of air (lbm/h)? d. How much net power is developed by the cycle (BTU/h)?
