The question gives this ..
The Reynolds number, Re, is a dimensionless group which characterizes the intensity of a flow. For large Re, a flow is turbulent; for small Re , it is laminar. For pipe flow, Re=u(density)D/mu, where D is pipe diameter and mu is dynamic viscosity.
It asks ..
If D and mu are fixed, what is the effect of increasing mass flow rate on Re?
and
If mass flow rate and mu are fixed, what is the effect of increasing D on Re?
Any help is appreciated,
Thanks!
