Heat Transfer

Q1: For what value of Prandtl number, the Col-burn analogy is valid ?

A 0.06 to 120

B 0.6 to 120

C 1 to 103

D l to 50

ANS:B - 0.6 to 120

The Colburn analogy is typically valid for Prandtl numbers ranging from 0.6 to 120. The Colburn analogy relates the heat transfer coefficient (Nu) to the friction factor (f) in forced convection flow. It is applicable for a wide range of Prandtl numbers, typically for fluids with Prandtl numbers greater than 0.6. Therefore, the correct option is: 0.6 to 120
