Heat Transfer By Convection = Heat Transfer By Conduction/Graetz Number
h_cn = h_co/Gr

What is convection?

Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid.

How to Calculate Heat transfer by convection given graetz number?

Heat transfer by convection given graetz number calculator uses Heat Transfer By Convection = Heat Transfer By Conduction/Graetz Number to calculate the Heat Transfer By Convection, The Heat transfer by convection given graetz number formula is defined as the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. Heat Transfer By Convection is denoted by h_cn symbol.

How to calculate Heat transfer by convection given graetz number using this online calculator? To use this online calculator for Heat transfer by convection given graetz number, enter Heat Transfer By Conduction (h_co) & Graetz Number (Gr) and hit the calculate button. Here is how the Heat transfer by convection given graetz number calculation can be explained with given input values -> 0.0125 = 10/800.
