## Prandtl Number of Oil

The Prandtl number is correlated with the temperature of the engine oil.The prandtl number is a dimensionless number defined as below: Pr = momentum diffusivity / thermal diffusivity = υ/α ‘υ’= momentum diffusivity or kinematic viscosity. ‘α’ = thermal diffusivity. The prandtl number of engine oil is high which lead to higher convective heat…
