Question $2$

Determine the dimensionless groups to be formed from the variables involved in the flow over a heated body with a cooling air flow $($i$.$e$.$ Forced Convection$)$ if there is a fixed temperature difference between the wall and the fluid. If the Heat Transfer coefficient

$($h$)$ is dependent upon the following variable:

Characteristic size of the heated body $()$

Free stream fluid velocity $($U$)$

Fluid density $()$

Fluid viscosity $()$

Fluid thermal conductivity $($k$)$

Fuid Specific Heat Capacity $($Cp
