Chapter 2, Problem 2.27P

Interpretation Introduction

Interpretation:

The Reynolds number for the given condition should be calculated and the flow should be explained.

Concept introduction:

Reynolds number ($\mathrm{Re}$) is defined as,

$\mathrm{Re}=Du\rho /\mu$

Where,

$D$ = Pipe diameter, $u$ = Fluid velocity, $\rho$ = Fluid Density, $\mu$ = Fluid viscosity

When the value of Reynolds number is less than about 2100, the flow is laminar. Reynolds numbers above 2100, the flow is turbulent.
