Hi, can you only help with part a of the following?
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.
Water stored in a large, well-insulated storage tank at 21oC, and atmospheric pressure is being pumped at steady state from this tank by a pump at the rate of 40m3/h. The motor driving the pump supplies energy at the rate of 8.5 k.W. The water is used as a cooling medium and passes through a heat exchanger where 255 k.W of heat is added to the water. The heated water then flows to a second large, vented tank, which is 25 m above the first tank. Determine the final temperature of the water delivered to the second tank.
Carbon dioxide gas is compressed at a steady state from a pressure of 16 lbf/in2 and a temperature of 32oF to a pressure of 50 lbf/in2 and a temperature of 130oF. The gas enters the compressor with a velocity of 30 ft/s and exits with a velocity of 80 ft/s. The mass flow rate is 3500 lb/hr. The magnitude of the heat transfer rate from the compressor to its surroundings is 5% of the compressor power input. Use the ideal gas model with cp = 0.21 Btu/lb·oR and neglect potential energy effects. A.) Determine the flow area at the inlet, in ft2, B.) and the power required by the compressor to work, in horsepower. Show complete solutions.
