Question

the value of biot number is very small (less than 0.01) when

Answer 1

The value of Biot number is very small (less than 0.01) when the conductive resistance of the solid is negligible.

Biot number is a number that is made use of in heat transfer calculations and has no unit. It is the ratio of the heat transfer resistance inside a body to the heat transfer resistance at the surface of the body.
