The pressure gradient for laminar flow through a constant radius tube is given by
Where
Determine the pressure drop for a 10-cm length tube for a viscous liquid
x, cm | 0 | 2 | 4 | 5 | 6 | 7 | 10 |
r, mm | 2 | 1.35 | 1.34 | 1.6 | 1.58 | 1.42 | 2 |
Compare your result with the pressure drop that would have occurred if the tube had a constant radius equal to the average radius.
Determine the average Reynolds number for the tube to verify that flow is truly laminar
