hii everyone,I have a design problem relating with heat exchangers.I know this was asked before but I couldn't find the answer.Here the question is attached
Middle East Technical University Department of Chemical Engineering Dec. 23, 2013 Ch.E. 327 – Heat and Mass Transfer Operations TERM PROJECT (Due Jan. 9, 2014) A heat exchanger is to be designed to condense 1100 kg/hr of steam at 150 kPa. For this purpose, cooling water at 50°C is available in sufficient quantity to accomplish the cooling. You are to design a shell-and-tube exchanger with steam in the shell and one tube pass as the condenser. Use information from the books listed below to 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 specifies water-flow rate, tube size, number of tubes, and tube length. Comment on your selection. REFERENCES 1.
