a) Explanation Write the energy balance for the steady-flow system. E ˙ in − E ˙ out = Δ E ˙ system (I) Here, rate of the rate of net energy transfer in to the control volume is E ˙ in , rate of net energy transfer exit from the control volume is E ˙ out , and rate of change in internal energy within the system is Δ E ˙ system . At steady state, rate of change in internal energy of system is 0. Substitute 0 for Δ E ˙ system in Equation (I) and rewrite the energy balance for the system as, E ˙ in − E ˙ out = 0 E ˙ in = E ˙ out m ˙ h 1 = Q ˙ o u t + m ˙ h 2 Q ˙ o u t = Q ˙ c h i c k e n = m ˙ c c P C ( T 1 − T 2 ) Q ˙ c h i c k e n = m ˙ c c P C ( T 1 − T 2 ) (II) Here, rate of heat transfer is Q in , mass flow rate of water is m ˙ , initial temperature is T 1 , final temperature is T 2 , initial enthalpy is h 1 , final enthalpy is h 2 , and specific heat of the water is c p b) To determine The rate of exergy destruction during the chilling process

37. The vertical shaft shown in Figure P12-37 is driven at a speed of 600 rpm with 4.0 hp entering through the bevel gear. Each of the two chain sprockets delivers 2.0 hp to the side to drive mixer blades in a chemical reactor vessel. The bevel gear has a diametral pitch of 5, a pitch diameter of 9.000 in, a face width of 1.31 in, and a pressure angle of 20°. Use SAE 4140 OQT 1000 steel for the shaft. See Chapter 10 for the methods for computing the forces on the bevel gear. Figure P12-37: P37-Bevel gear drive with two chain sprockets Each problem includes the following details: ■Design the complete shaft, including the specification of the overall geometry and the consideration of stress con- centration factors. The analysis would show the minimum acceptable diameter at each point on the shaft to be safe from the standpoint of strength. Homework Problems 12-24, 12-35, and 12-37 from textbook, done in spreadsheet form. Place drawings of the load, shear, and bending moment body diagrams…

35. The double-reduction, helical gear reducer shown in Figure P12-35 transmits 5.0 hp. Shaft 1 is the input, rotating at 1800 rpm and receiving power directly from an electric motor through a flexible coupling. Shaft 2 rotates at 900 rpm. Shaft 3 is the output, rotating at 300 rpm. A chain sprocket is mounted on the output shaft as shown and delivers the power upward. The data for the gears are given in Table 12-5. Each gear has a 1412° normal pressure angle and a 45° helix angle. The combinations of left- and right-hand helixes are arranged so that the axial forces oppose each other on shaft 2 as shown. Use SAE 4140 OQT 1200 for the shafts.
