Describe Nusselt Number, Reynolds Number and Prandtl Number. Get the relation between these three for a circular cylinder losing heat in forced convection to the air flowing around it Use dimensional analysis. create an expression for momentum equation.
A horizontal heated plate at 200 oC facing upwards has been placed in still air at 20 oC. If the area of the plate is / m2 . Determine heat loss by free convection. The convective heat transfer co-efficient is provided by H= 0.35(Ø)0.25W/ m2K Where Ø is film temperature.
