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

Nusselt number

So equating these two equation.. one can find heat transfer co-efficient on fluid side.

Hope you have understood the above co-relations..
