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

A steel alloy contains 95.7 wt% Fe, 4.0 wt% W, and 0.3 wt% C.

b. A horizontal cantilever of effective length 3a, carries two concentrated loads W at a distance a from the fixed end and W' at a distance a from the free end. Obtain a formula for the maximum deflection due to this loading using Mohr's method. If the cantilever is 250 mm by 150mm steel I beam, 3 m long having a second moment of area I as 8500 cm4, determine W and W'to give a maximum deflection of 6 mm when the maximum stress due to bending is 90 Mpa. Take Young's modulus of material E as 185 Gpa.
