Refrigerant 134a enters a horizontal pipe operating at steady state at 40°C, 300 kPa, and a velocity of 25 m/s. At the exit, the temperature is 50°C and the pressure is 240 kPa. The pipe diameter is 0.055 m. Determine: (a) the mass flow rate of the refrigerant, in kg/s, (b) the velocity at the exit, in m/s, and (c) the rate of heat transfer between the pipe and its surroundings, in kW.
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.
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).
Argon gas flows through a well-insulated nozzle at steady state. The temperature and velocity at the inlet are 550°R and 150 ft/s, respectively. At the exit, the temperature is 460°R and the pressure is 40 Ibf/in?. The area of the exit is 0.0085 ft?. Use the ideal gas model with k = 1.67, and neglect potential energy effects. Determine the velocity at the exit, in ft/s, and the mass flow rate, in Ib/s.
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
