Answer 1

For a given value of Nusselt number, the convective  surface coefficient h is directly proportional to​ Thermal conductivity.

Explanation:

• The convective heat transfer coefficient is primarily dependent upon the physical properties of the fluid and the physical situation.  

• Values of convective surface coefficient h, have been measured and tabularized for commonly met fluids and flow conditions.

• The convective surface coefficient is directly proportional to thermal conductivity k and inversely proportional to suggestive length.
