Free Prandtl Number Calculator: Quick and Easy Online Tool

What is prandtl number?

The Prandtl number (Pr) is a dimensionless number in fluid dynamics and heat transfer that represents the ratio of momentum diffusivity (viscosity) to thermal diffusivity. It helps to describe the relative thickness of the velocity boundary layer to the thermal boundary layer in a fluid.

A low Prandtl number (Pr < 1) means heat diffuses quickly compared to momentum, while a high Prandtl number (Pr > 1) indicates that momentum diffuses faster than heat. It is commonly used in heat transfer and fluid flow problems, particularly for assessing the behavior of different fluids in thermal systems.

How to Use the Prandtl Number Calculator Tool

Gather Necessary Input Values

Calculator, you’ll need the values for dynamic viscosity (μ), thermal conductivity (k), and specific heat capacity (Cp). These are key properties of the fluid you're analyzing.

Enter Dynamic Viscosity (μ)

Input the dynamic viscosity of the fluid in the appropriate field. This is usually measured in pascal-seconds (Pa·s) or poise (P), depending on the unit system you are using.

Input Thermal Conductivity (k)

Next, enter the thermal conductivity of the fluid in watts per meter-kelvin (W/m·K). This property measures the fluid's ability to conduct heat.

Specify Specific Heat Capacity (Cp)

Now, input the specific heat capacity of the fluid at constant pressure in joules per kilogram-kelvin (J/kg·K). This reflects how much energy is needed to raise the temperature of a unit mass of the fluid by one degree.

Calculate

Once all values are entered, this calculator will automatically compute the Prandtl number (Pr), which is a dimensionless number that represents the ratio of momentum diffusivity to thermal diffusivity.

Use Results

To understand the heat transfer behavior in the fluid flow, compare the calculated Prandtl number to make further decisions to see whether the flow is conduction-control or convection-control.

Clear Button

This button that allows you to clear the input fields and start a new calculation. This button is helpful when you need to perform multiple time calculations or make changes to the input values.

Conclusion

Therefore, since a Prandtl Number Calculator is a handy tool in estimating the appropriate balance of momentum and thermal diffusivity in the dynamics of fluids.
