Nanofluids are a class of heat transfer fluids which are created by dispersing solid nanoparticles in traditional heat transfer fluids. This work describe an experical design and a numerical method to illustrate the forced convective heat transfer using traditional fluid and Zinc Oxide/Water (0.5%v/v) nanofluid in double-pipe heat exchanger utilizing commercially available equipment. The test results are shown that the heat transfer rate and heat transfer coefficients of the nanofluid is higher than that of the base liquid (i.e., water). Increasing in the overall heat transfer coefficient is more forcible at high cold flow rate for a given hot fluid flow rate. The heat transfer rate and heat transfer coefficients, finally increase with increase in mass flow rates of hot and cold streams
