    4.75 An air-conditioning system is shown in Fig. P4.75 in which air flows over tubes carrying Refrigerant 134a. Air enters with a volumetric flow rate of 50 m³/min at 32°C, 1 bar, and exits at 22°C, 0.95 bar. Refrigerant enters the tubes at 5 bar with a quality of 20% and exits at 5 bar, 20°C. Ignoring heat transfer at the outer surface of the air conditioner, and neglecting kinetic and potential energy effects, determine at steady state (a) the mass flow rate of the refrigerant, in kg/min. (b) the rate of heat transfer, in kJ/min, between the air and refrigerant. 3 R-134a P3 = 5 bar x3 = 0.20 Refrigerant 134 Air P₁ = 1 bar T₁ =32°C 305 K (AV), 50 m³/min = Air 2-P2 = 0.95 bar T2 22°C 295 K = = 4 R-134a P4 = 5 bar T4=20°C
    4.42 Steam enters a well-insulated turbine operating at steady state at 4 MPa with a specific enthalpy of 3015.4 kJ/kg and a velocity of 10 m/s. The steam expands to the turbine exit where the pressure is 0.07 MPa, specific enthalpy is 2431.7 kJ/kg, and the velocity is 90 m/s. The mass flow rate is 11.95 kg/s. Neglecting potential energy effects, determine the power developed by the turbine, in kW.
    The two blocks A and B have weights WA = 60 lb and WB = 10 lb. If the kinetic coefficient of friction between the incline and block A is μk = 0.2, determine the speed of A after it moves 3 ft down the plane starting from rest. Neglect the mass of the cord and pulleys. 3 B
