Question

The Reynolds number is a dimensionless quantity used in fluid mechanics. It is defined as:where d is the pipe diameter, v is the fluid velocity, is the fluid density, and is the fluid viscosity. In American Engineering units (ft, sec, lbm), what are the units of the viscosity? Hint, all the units should cancel out to produce the dimensionless Reynolds number.

Answer 1

Lb(force)•second/ft^2
