Investigate the effect of tube roughness on flow rate by computing the flow generated by a pressure difference \(\Delta p=100 \mathrm{kPa}\) applied to a length \(L=100 \mathrm{~m}\) of tubing, with diameter \(D=25 \mathrm{~mm}\). Plot the flow rate against tube relative roughness \(e / D\) for \(e / D\) ranging from 0 to 0.05 (this could be replicated experimentally by progressively roughening the tube surface). Is it possible that this tubing could be roughened so much that the flow could be slowed to a laminar flow rate?
