Heat Transfer

Q1:

The equation, (NSt x N2/3Pr) = f/2, is the __________ analogy.

A Colburn

B Reynolds

C Prandtl

D none of these.

ANS:A - Colburn

The equation 2(NSt×N2/3Pr)=2f​ represents the Colburn analogy. In heat transfer and fluid mechanics, the Colburn analogy relates the Nusselt number (NSt), Reynolds number (Re), and Prandtl number (Pr) for heat transfer in a fluid flow. It's an empirical correlation used to estimate heat transfer coefficients in forced convection flow. So, the correct answer is: Colburn.
