In this study, we proposed a theoretical investigation on the temperature dependent viscosity effect on magnetohydrodynamic dissipative nanofluid over a truncated cone with heat source/sink. The involving set of nonlinear partial differential equations is transforming to set of nonlinear ordinary differential equations by using self-similarity solutions. The transformed governing equations are solved numerically using Runge-Kutta based Newton�s technique. The effects of various dimensionless parameters on the skin friction coefficient and the local Nusselt number profiles are discussed and presented with the support of graphs. We also obtained the validation of the current solutions with existing solution under some special cases. The water based titanium alloy have a lesser friction factor coefficient as compared with kerosene based titanium alloy, whereas the rate of heat transfer is higher in water based titanium alloy compared with kerosene based titanium alloy. From this we can highlight that depending on the industrial needs cooling/heating choose the water or kerosene based titanium alloys.
