Question 1

What Reynold’s number indicates turbulent flow? what effect does diameter have on the Reynold’s number?

Answer 1

R > 4000 is associated with turbulent flow
R< 2000 is laminar flow

As diameter increases, so does the Reynold’s number, meaning that increased radius leads to increased turbulent flow

Question 2

What gas property is associated with laminar flow? Turbulent flow?

Answer 2

Laminar = viscosity

Turbulent flow = density
