Nusselt number is the ratio of the temperature gradient at the wall to that across the entire pipe.
The Nusselt number is the ratio of convective to conductive heat transfer across a boundary.
Nu = hL/K.

The Nusselt number for fully developed (both thermally and hydrodynamically) laminar flow through a circular pipe, where the wall heat flux is constant.

Alpesh Solanki said:   4 years ago
Nu is product of Heat flux at wall and Entire Length.

Alpesh Solanki said:   4 years ago
Nu = hL/K= rate of wall HT/rate of HT by conduction.
