Homework Answers
The factors which affect the convection heat transfer coefficient are:
Velocity of the fluid
Type of fluid flow(Laminar or turbulent)
Geometric shape
Surface condition(surface roughness)
Viscosity of the fluid
Thermal conductivity of the fluid
Hence Density of the solid body doesn't affect the convection heat transfer coefficient
