Heat transfer by convection given graetz number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Heat Transfer by Convection = Heat Transfer by Conduction/Graetz Number
h_cn = h_co/Gr
This formula uses 3 Variables

Variables Used

Heat Transfer by Convection - Heat transfer by convection is heat transfer by mass motion of a fluid such as air or water.
Heat Transfer by Conduction - Heat transfer by conduction is the transfer of heat by means of molecular excitement within a material without bulk motion of the matter.
Graetz Number - Graetz number is used in determining the thermally developing flow entrance length in ducts.

STEP 1: Convert Input(s) to Base Unit

Heat Transfer by Conduction: 10 --> No Conversion Required
