Nusselt Number Formula
The following equation can be used to calculate the Nusselt number of a given system.
N = h * L / k
- Where N is the nusselt number
- h is the convective heat transfer coefficient
- L is the characteristic length
- k is the thermal conductivity of a fluid
Nusselt Number Definition
A Nusselt number is a measure of the rate of heat transfer between a moving fluid and a solid body.
Nusselt Number Example

FAQ
The Nusselt number is a dimensionless unit used to calculate heat transfers between a moving fluid and a solid body.
The Nusselt number is calculator by multiply the convective coefficient by the length, and then dividing by the conductivity of the moving fluid.
The convective heat transfer coefficient is the rate at which the container conducts heats with the outside atmosphere.
