Refrigerant 134a enters an insulated diffuser as a saturated vapor at 80oF with a velocity of 1200 ft/s. The inlet area is 1.4 in2. At the exit, the pressure is 400 lbf/in2 and the velocity is negligible. The diffuser operates at steady state and potential energy effects can be neglected. Determine the mass flow rate, in lb/s, and the exit temperature, in oF.
I am getting lost in this practice problem for thermodynamics - thank you!
Air at 100 kPa and 280K is compressed steadily to 600 kPa and 400K in an air compressor. The mass flow rate of air through the compressor is 0.02 kg/s and the compressor a heat loss of 16 kJ/kg from the compressor occurs. Assuming steady state steady flow conditions and ideal gas behavior (with constant specific heats, Cp=1.009 kJ/kgK, R=0.287 kJ/kgK, determine:
a) The necessary power in put to the compressor(kW).b) The volumetric flow rate of air at the exit of the compressor (m3/s).
Air exits a turbine at 150 kPa and 150°C with a volumetric flow rate of 4,000 liters/s.
Modeling air as an ideal gas, determine the mass flow rate, in kg/s.
