LAMINAR & TURBULENT FLOWS

laminar and turbulent flow

Reynolds number

EXAMPLE

An oil with a viscosity of μ= 0.40 N·s/m 2 and density ρ= 900 kg/m3 flows in a pipe of diameter D= 0.20 m. The given volumetric flow rate is 2.0 ×10^-5 m3/s. Characterize the flow of the fluid.

Come test yourself and post your answer below :)

What is the minimum speed a fluid needs to achieve laminar flow, given:

Density = 1890 kg/m3

Vicosity = 1.5 cP

Diameter = 0.75 m
