An experimental investigation on the heat transfer coefficient h0 in an cylindrical agitated vessel using immiscible liquid systems was made at different operating conditions. Spiral helical copper coil was used inside in the agitated vessel as a provision of cooling water system. The effect heat transfer coefficient h0 on the fundamental parameter viz., agitator speed, liquid properties (volume percent of dispersed phase), cooling water flow rate and the position of agitator were analyzed in the present study and an generalized empirical correlation was proposed for heat transfer coefficient in terms of Nusselt number (NJ combined with the Reynolds number (NJ, Prantle number (NP|) and volume ratio cp/(1 -cp) and the depth of turbine (H./D,).
