The effect of heatflow and pressure drop on performance of tube heat exchanger was experimentally analysed and the process parameters were optimized. The process parameters were chosen for the experiment are velocity (0.5 to 1.0), spacing (0.5-0.7) and ellipticity (0.75-1.25). Theoutcomes of the experiment like heat transfer and pressure drop were measured at different conditions ordered in L9 orthogonal array.The main aim of this work is increase the heat transfer rate and reduce the pressure drop during functioning of tube heat exchanger. The ANOVA analysis was performed to identify the each parameter impact on outcomes. The experimental results reported that, at optimized condition (0.5-0.7-1.25) higher heat transfer, lower pressure drop at (1.0-0.7-1.25) wasobserved and reported. Finally single order regression equation was also developed for estimate the heat flow and pressure drop.
