Steam with a quality of 0.7, pressure of 1.5 bar, and flow rate of 10 kg/s enters a steam separator operating at steady state. Saturated vapor at 1.5 bar exits the separator at state 2 at a rate of 6.9 kg/s while saturated liquid at 1.5 bar exits the separator at state 3. Neglecting kinetic and potential energy effects, determine the rate of heat transfer, in kW, and its associated direction.

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.

Refrigerant 134a enters an insulated diffuser as a saturated vapor at 80°F with a velocity of 1400 ft/s. The inlet area is 1.4 in². At the exit, the pressure is 400 lb/in² and the velocity is negligible. The diffuser operates at steady state and potential energy effects can be eglected. Determine the mass flow rate, in lb/s, and the exit temperature, in °F. Step 1 Your answer is correct. Determine the mass flow rate, in lb/s. m = 28.887 Hint Step 2 lb/s. Determine the exit temperature, in °F. T₂ = i OF Attempts: 1 of 4 used

Refrigerant 134a enters an air conditioner compressor at 4 bar, 20 degrees celsius, and is compressed at steady state to 12 bar, 80 degrees celsius. The volumetric flow rate of the refrigerant entering is 5m3/min. The work input to the compressor is 75 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.
