Question

The Biot number can be thought of as the ratio of

A.The conductive thermal resistance to the convective thermal resistance
B. The convective thermal resistance to the conductive thermal resistance
C. The thermal energy storage capacity to the conduction thermal resistance
D. The thermal energy storage capacity to the convection thermal resistance
E. None of the above

Answer 1

The Biot number can be thought of as the ratio of (A) The conductive thermal resistance to the convective thermal resistance. It is used to determine the relative importance of conduction and convection in heat transfer analysis.

Step-by-step explanation:

The Biot number can be thought of as the ratio of (A) The conductive thermal resistance to the convective thermal resistance. The Biot number is used in heat transfer analysis to determine the relative importance of conduction and convection in a system. It compares the resistance to heat transfer through a material (conductive thermal resistance) to the resistance to heat transfer by convection.

For example, in a situation where convection is dominant, the Biot number will be large because the resistance to heat transfer through the material is small compared to the resistance to heat transfer by convection.
