OK..
Now the big question.. the flow parameter Re & thermal parameter Pr, how they connects to HEAT TRANSFER???
So for our help.. Mr. Nusselt has created Nusselt Number!!
The traditional dimensionless form Nusselt number Nu, which may be defined as the ratio of convection heat transfer to fluid conduction heat transfer under the same conditions.
Nusselt number Nu can be calculated as
Nu = X . Re^y.Pr^z
Where X , y, z parameters are depends upon geometry, nature of flow, flow regime etc
Nusselt Number can also calculated as
So equating these two equation.. one can find heat transfer co-efficient on fluid side.
Hope you have understood the above co-relations..
