1. Refrigerant 134a as saturated vapor at 210°C enters a compressor operating at steady state with a mass flow rate of 0.3 kg/s. At the compressor exit the pressure of the refrigerant is 5 bar. Stray heat transfer and the effects of motion and gravity can be ignored. If the rate of exergy destruction within the compressor must be kept less than 2.4 kW, determine the allowed ranges for (a) the power required by the compressor, in kW, and (b) the exergetic compressor efficiency. Let T0 5 298 K, p0 5 1 bar.
2. For the turbine-compressor arrangement of Problem 6.164, determine the exergetic efficiency for (a) the turbine, (b) the compressor, (c) an overall control volume enclosing the turbine and compressor. Let T0 5 300 K.

Air enters a steady-flow turbine at 1600 K and exhausts to the atmosphere at 1000 K. The second law efficiency is 85%. What is the turbine inlet pressure?
Suppose you are working for a start-up company that is designing a very new and innovative product. Does the client–user–designer model still apply? Who is your client in this case? Since you don’t have any customers yet, who are the users and how ca..
Horsepower and efficiency of three-phase motor, If a fully loaded 440V, three-phase motor draws 12.4 A at 86% power factor (pf). It's speed is 1730 rpm and its torque output to a mechanical load is 29.1 lb-ft x 1.356 = 39.5 Nm.
Consider a cold aluminium canned drink that is initially at a uniform temperature of 3°C. The can is 12.5 cm high and has a diameter of 6 cm. The combined convection/radiation heat transfer coefficient between the can and the surrounding air at 25°C ..
A piston-cylinder device contains steam initially at 1 Mpa, 450 degrees celcius and 2.5 m^3. Steam is allowed to cool at constant pressure until it first starts condensing. Show the process on T-v diagram with respect to saturation lines and determin..
