9.15(35 pts) Repeat Prob. 9–14 using constant specific heats at room temperature.a) do not have to do the T-s diagram (unless you want to) 9-14 An air-standard cycle with variable

specific heats is executed in a closed system with 0.003 kg of air and consists of thefollowing three processes: 1-2 v = constant heat addition from 95 kPa and 17°C to 380 kPa 2-3 Isentropic expansion to 95 kPa 3-1 P == constant heat rejection to initial state (a) Show the cycleon P-U and T-s diagrams. (b) Calculate the net work per cycle, in kJ. (c) Determine the thermal efficiency.
