Consider the fully developed laminar flow due to gravity of water in a vertical circular tube. Assume atmospheric pressure at inlet and outlet. Show that the relationship between diameter and Reynold's number is
D = (32*Re*v2/g)⅓
I know that Re = ρvD/μ
I was thinking that perhaps I have to use Bernoulli's equation,
v12+P/ρ+gz1 = v22+P/ρ+gz2
But beyond that I'm not sure. Thanks in advance!
