Spelling "Wolfarm" correctly was progress; "demostration" could be next.

Read some books in fluid dynamics and convection heat transfer.

You can find other dimensionless numbers/parameters by graphical means.

Dear Mr. kahaten,

Nusselt No Equation is (0.0023) x Re0.8 x Pr0.4

In this equation the Friction is involved in the Reynold's No. which is (4 x f x L x v^2)/ 2 x g x D

Then how can you equate with them.

Frankly I have no sufficient information about this topic, but I saw some articles talking about that by using LAB Fit program. And I think that the general form of Nusselt Number . is (X) x Ren x Prm and the variable changing depend on the type of case.

Thank you so much for your attention Mr. dhayanandhan

Use real numbers.

Math gets a whole lot easier when you stop trying to do it with the alphabet.
