This investigation has revealed that unequal multi-pass 1:2 and 1:3 heat exchanger arrangements with the same sized tubes in each pass and the same total surface area are less efficient thermally than equal pass systems. In addition, the tube side pressure drop is least for the equal pass arrangements.
