Question

Find the Reynolds number if a fluid of viscosity 0.4 Ns/m2 and relative density of 900 kg/m3 through a 20 mm pipe with a velocity of 2.5 m/s. Is the flow Laminar or Turbulent

Answer 1

Answer:

Given : μ=0.4Ns/m

2

, ρ=900kg/m

3

, l=20mm=0.02m, v=2.5m/s

Reynolds number N=

μ

=

0.4

900×2.5×0.02

=112.5
