It is also Biot no= hL/k.

Nusselt Number is the correct answer. I agree.

Seya said: (Aug 28, 2017)  
Biot number is also true.

Pail said: (Oct 21, 2018)  
Yes, right @Seya.

Vinod said: (Jun 20, 2019)  
Biot number is right.

Biot number is for solids. There is no convection in solids.

The analytical formula is the same for both of them which (hL/k) but k in Nu number is the thermal conductivity of fluid wherein Bi, it is the thermal conductivity of solid not fluid.
