# Prandtl Number Calculator

This sophisticated online Prandtl Number Calculator is designed to apply the supplied formula to compute diffusion in flowing systems. Ludwig Prandtl, a German physicist, was the genesis for the name.

#### Input

#### Output

#### Formula

**v**= Kinematic Viscosity**α**= Thermal Diffusivity**Pr**= Wetted Perimeter

#### Defination / Uses

The sign 'v' stands for Kinematic Viscosity. Stokes are generally used to evaluate kinematic viscosity. The viscosity is a measure of the adhesive/cohesive or frictional fluid property and is defined as the fluid resistance to shear or flow. The kinematic formula is used to compute the fluid resistance or density using our advanced online Kinematic Viscosity Calculator.

#### Formula

**α**= Thermal Diffusivity**Pr**= Wetted Perimeter**v**= Kinematic Viscosity

#### Defination / Uses

A dimensionless number is referred to as the Prandtl Number. The ratio of momentum diffusivity (kinematic viscosity) to thermal diffusivity is known as kinematic viscosity. In a nutshell, the Prandtl Number is the ratio of the thermal conductivity in fluid flow to the product of the coefficient of viscosity and the specific heat under constant pressure.

Thats it! You will get your answer in just a second.

This calculator will help you to do quick and accurate calculation as compared to do it manually. The Prandtl number is calculated as the ratio of momentum to thermal diffusivity. It can be used to determine the thermal conductivity of gases at high temperatures, where measuring it experimentally is problematic due to convection current creation. The Prandtl number is represented by the sign Pr. Upper given formulla will help you for manually calculations. No sign-up, registration OR captcha is required to use this tool.
