Average Nusselt number upto length L given Reynolds number Formula Elements

Variables

Average Nusselt Number

Average Nusselt number is the ratio between heat transfer by convection (α) and heat transfer by conduction alone.

Symbol: Nu_avgL

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Average Nusselt Number

Reynolds Number

The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.

Symbol: Re

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Reynolds Number

Prandtl Number

The Prandtl number (Pr) or Prandtl group is a dimensionless number, named after the German physicist Ludwig Prandtl, defined as the ratio of momentum diffusivity to thermal diffusivity.

Symbol: Pr

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.
