Which of the following is least likely to affect the convection heat transfer coefficient? a)- thermal conductivity of the fluid b)-geometry of the solid body c)-the roughness of the solid surface d)-type of fluid motion (laminar or turbulent) e)- fluid velocity f)- density of the solid body g)-dynamic viscosity of the fluid

f)Density of the solid body

Explanation:

We know that heat transfer due to convection is given by

            Q=hAΔT

Where

A is the area ,which represent the geometry of solid body or surface.

h is the heat transfer coefficient which depends on

                             1.Thermal conductivity of fluid

                             2.Motion of fluid

                             3.Type of fluid flow(Laminar or Turbulent)

                             4.Viscosity of fluid

                             5.Surface condition

So from the above parameters ,we can say that heat transfer due to convection does not depends on density of the solid body.

answer: i have no clue tbh

it happens to me to tho

answer:

ok yeah for me again
