Question

Write a question in thermodynamics term for the given solution.

Solution (partial) : Re = (density)(velocity)(characteristic length) / (dynamic viscosity)

Units in SI system are density [kg/m3 ] and dynamic viscosity [Pa∙s]

Velocity and length have SI units of .... M, L and t for dimension symbols for mass, length and time, respectively.

Answer: dim (Re) = [ 1 ], Reynolds number is a dimensionless parameter.
