Air, modeled as an ideal gas, is compressed at steady state from 1 bar, 300 K, to 5 bar, 500 K, with 120 kW of power input. Heat transfer occurs at a rate of 16 kW from the air to cooling water circulating in a water jacket enclosing the compressor. Neglecting kinetic and potential energy effects, determine the mass flow

Refrigerant 134a enters an air conditioner compressor at 4 bar, 20°C, and is compressed at steady state to 12 bar, 80°C. The volumetric flow rate of the refrigerant entering is 7 m3/min. The work input to the compressor is 105 kJ per kg of refrigerant flowing.Neglecting kinetic and potential energy effects, determine the magnitude of the heat transfer rate from the compressor, in kW.

Refrigerant 134a enters an air conditioner compressor at 4 bar, 20°C, and is compressed at steady state to 12 bar, 80°C. The volumetric flow rate of the refrigerant entering is 4.5 m³/min. The work input to the compressor is 72 kJ per kg of refrigerant flowing. Neglecting kinetic and potential energy effects, determine the magnitude of the heat transfer rate from the compressor, in kW.

If steam flows through a nozzle at steady-state, entering the nozzle with a pressure of 0.5 MPa and a temperature of 673 K, where H = 3272 kJ/kg, and exiting at 0.1 MPa and 623 K, where H = 3176 kJ/kg, what is its exiting velocity (in m/s)? Assume that the heat loss is 10% of the change in kinetic energy.

Air enters a diffuser operating at steady state at 540°R, 15 Ilbf/in.?, with a velocity of 600 ft/s, and exits with a velocity of 60 ft/s. The ratio of the exit area to the inlet area is 6. Assuming the ideal gas model for the air and ignoring heat transfer, determine the temperature, in °R, and pressure, in Ibf/in.?, at the exit.

Air enters a compressor operating at steady state at 1.05 bar, 300 K, with a volumetric flow rate of 39 m³/min and exits at 12 bar, 400 K. Heat transfer occurs at a rate of 6.5 kW from the compressor to its surroundings. Assuming the ideal gas model for air and neglecting kinetic and potential energy effects, determine the power input, in kW.
