Empirical Investigation And Comparison Of Different Viscosity Liquids With Increasing Temperature

Viscous fluids are identified to have viscosity that varies with temperature, which affects the flow. Some fluids have a 10-12% variation in viscosity per °C change in temperature. For several production engineering applications it is necessary to retain both flow and temperature of the fluid at a steady value. Different flow rates of the fluid may be essential at the same temperature. The main reason of this analysis is to expirically study kinematic viscosity for various types of oils namely engine oil, refined oil and coconut oil. The Saybolt Viscometer is used to study the characteristics for its usage in the automobile machine parts. We were able to conclude that refined oil gave the lowest viscosity, the refined oil gave the lower viscosity and Engine oil was higher than the other two. It is therefore proposed that refined oil can be used as a lubricant, as the temperature increases the viscosity.
