A window air Conditioning is operating with Refrigerant-R22. An engineer wants to collect data on the flow rate of the refrigerant. The refrigerant is passed through one inlet and one exit pipe (Flgure 2) of diameter 3 cm steadily at a pressure of 2.5 bar and temperature of 5 °C with a velocity of 3 m/s. Due to heat gain from its surrounding, the refrigerant leaves the pipe at a pressure of 2 bar and temperature of 25 °C. Figure 2. One inlet one exit pipe For the refrigerant, determine (a) The volume flowrate at the pipe inlet (b) The mass flow rate The velocity and volume flow rate at the pipe exit

8. In a steady flow apparatus 135 KJ of work is done by each kg of fluid. The specific volume of the fluid, pressure, and speed at the inlet are 0.30 m³/kg, 600 kPa, and 16m/s. The inlet is 32m above the floor and the discharge pipe are at floor level. The discharge conditions are 0.60 m³/kg, 1 bar, and 270 m/s. The total heat loss between the inlet and discharge is 9KJ/kg of fluid. In flowing through this apparatus, does the specific internal energy increase or decrease? And by how much?
14A fluid flows at a speed of 7.5 m/s in a pipe with a diameter of 35 cm. What is the power, in W, of the pump to overcome the irreversible pressure drop when the pressure drop along the pipe is calculated to be 6300 Pa?

Steam enters a turbine with a pressure of P1= 4888 kPa, specific internal energy u1= 3612 kJ/kg, mass flow rate of 7.5kg/s and density of 1.112 kg/m3. Steam leaves at P2 = 224 kPa with a density of 4.5kg/m3 and a specific internal energy of u2= 1224 kJ/kg. Heat loss from the device by radiation is 50KJ/kg. Neglecting the changes in kinetic and potential energies, determine the power produced by the system.
Consider a gate-type valve with which the flow of air flowing at the inlet at 27 °C and 5 atm is controlled and is throttled down to 1 atm. If the valve is subjected to 2 kJ/kg of heat from a nearby external source and V₁ >>V2, determine the air outlet temperature, in °C.
