The Reynolds number is a dimensionless group defined for a fluid flowing in a pipe
Dup/μ
Re =
where D is pipe diameter, u is fluid velocity, p is fluid density, and µ is fluid dynamic viscosity. When
the value of the Reynolds number is less than about 2100, the flow is laminar-that is, the fluid
flows in smooth streamlines. For Reynolds numbers above 2100, the flow is turbulent, characterized
by a great deal of agitation.
Liquid methyl ethyl ketone (MEK) flows through a pipe with an inner diameter of 2.067 inches at an
average velocity of 0.48 ft/s. At the fluid temperature of 20°C the density of liquid MEK is 0.805
g/cm³ and the viscosity is 0.43 centipoise [1 cP = 1.00 x 10-³ kg/(m.s)]. Without using a calculator,
determine whether the flow is laminar or turbulent. Show your calculations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc1a44390-55e9-4a9d-9107-98b65593a58b%2F58c560ea-e0f8-4d47-aa58-05613fbc35c5%2Ffydrx2a_processed.jpeg&w=3840&q=75)
