A heat exchanger is to be designed to condense 1100 kg/hr of steam ay 150 kPa. For this purpose, cooling water at 50 degrees celsius is available in sufficient quantity to accomplish the cooling. You are to design a shell-ad-tube exchanger with steam in the shell and one tube pass as the condenser. Calculate the convection coefficients for condensation and forced flow through the tubes. Select several alternatives for the tube bank and tube size, determine the length of the heat exchanger, and calculate the pressure drop through the tubes for each selection. Recommend a final design that specidies water-flow rate, tube size, number of tubes, and tube length. Comment on your selection.
