ME 3322 Thermodynamics Name: Unit: 5 Type: 5 ID: 0110.1 Date: Air enters the compressor of a steady Brayton cycle refrigeration plant (point 1) at 270 K, 140 kPa, 0.8 m 3 /s and is compressed to 420 kPa. The refrigeration capacity of the plant is 65 kW. The turbine and compressor isentropic efficiencies are 0.92 and 0.78, respectively. Determine the mass flow rate of the air, the temperatures at the compressor outlet, turbine inlet, and turbine outlet, the net power input, and the coefficient of performance.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
