Question

A fluid of density 1400 kg/m^3 and viscosity of 0.9 kg/m.s flows through an 80 mm diameter pipe with a velocity of 5 m/s. What type of flow exists in the pipe? Justify your answer.

Answer 1

Answer:

laminar

Explanation:

to know what kind of flow there is we must calculate the number of reynolds

Re=(ρVD)/υ

Re=Reynolds

ρ=Density

D=Diameter

υ=viscosity

Re=(1400x5x0.08)/0.9=622.2

we know that if the number of reynolds is less than 2100 the flow is laminar
