Design a concentric tube heat exchanger (in co-current configuration) to heat 1000 cm3/ min of water from 30oC to 45oC flowing in the shell, using water at 65oC flowing in the tube. The heating water should not exit with temperature above 55oC. Choose a suitable range of inner pipe (copper material) diameters for heat exchanger, assume suitable inner tube thickness and outer tube diameter and show selection of parameters and dimensions for an optimum design.
