Question

Is dimensionless Reynolds number is an important parameter?

(a) False

(b) True

The question was posed to me in class test.

My question comes from Laminar Flow topic in section Incompressible Flow over Airfoils of Aerodynamics

Answer 1

Correct choice is (b) True

Easiest explanation: The flow occurring in a fluid in a channel is important in fluid- dynamics problems and subsequently affects heat and mass transfer in a fluid system. The dimensionless Reynolds number is an important parameter in the equations that describe whether fully developed flow conditions lead to laminar.
