Distinguish Semi-infinite and finite solids and, discuss on problem solving procedure of same 2. Enumerate the numerical solving procedure of bank of tubes, with necessary steps involving in it 3. Draw and explain , Lumpled analysis problems solving procedure using Heisler chart with the help of HMT Data book 4. Air at 20oC flowing over a flat plate at velocity of 3m/s. If the flat plate is maintained at 60C.Calculate the heat transfer per unit width of plate assuming length of the plate is equal to 2m. Calculate the following at x=300mm(i)Hydrodynamic Boundary layer(ii)Average friction coefficient(iii)Wall shear stress (iv)Total Drag Force 5. The outer surface of cylindrical vertical tube having 25cm diameter is exposed to saturated steam of mass flow rate 65Kg/hr at 1.7 bars for condensation. The surface temperature of the tube is maintained at 85 oC. Calculate the following (i)Length of the tube (ii)Thickness of the condensate layer to condense 6. Discuss, Industry case Elaborately on External convective flow considering Laminar and Turbulent, also deliberate the problem-solving procedure of the same with help of Heat and mass Transfer data book
