The present work investigated the effect of mass flow rate, hot and cold fluid temperature on total heat transfer and effectiveness for shell and tube heat exchanger. In addition, the effect of Reynolds number and type of fluid on heat transfer coefficient and effectiveness was studied. Increasing Reynolds number by 500 from 7000, 8% increasing in heat transfer coefficient has been observed. While 7% increase in Reynolds number, effectiveness has been increases by 5%. Nusselt number change shows higher effect on effectiveness for shell side as compared to tube side. A MATLAB program has been formulated to calculate the result by changing different parameters. During experimental observation, the rate of heat transfer is 143.74 kW and effectiveness of shell and tube heat exchanger is 0.50. The optimum heat transfer through shell and tube heat exchanger had been achieved at 0.0084 m2 surface area of tube and 27 number of tube.
