Question

Laminar flow and turbulent flow depends on __________

(a) Reynolds number

(b) Prandtl number

(c) Nusselt number

(d) Archimedes number

I got this question by my college professor while I was bunking the class.

My question is taken from Fluid Flow Theory topic in division Fluid Flow Theory & Applications of Food Processing Unit Operations

Answer 1

Right option is (a) Reynolds number

To explain I would say: The Reynold number (R) is a dimensionless quantity that is used to determine whether the fluid is following laminar flow (R<2300), transition flow (23004000).
