A liquid of viscosity of 0.03 N s m 2 is flowing under laminar conditions through a convergent, tapered tube for which the tube diameter changes linearly with length. The tube length is 0.50 m and its diameter varies from 0.01 m at the entrance to 0.005 m at the exit. Determine the pressure drop which is required to maintain the flow at a rate of 10-7 m3 s-1. The effect of kinetic energy due to the change in velocity in the tube may be neglected. Show the derivation of the final eauation used in solving this problem.

Question
A liquid of viscosity of 0.03 N s m2 is flowing under laminar conditions through a
convergent, tapered tube for which the tube diameter changes linearly with length.
The tube length is 0.50 m and its diameter varies from 0.01 m at the entrance to
0.005 m at the exit. Determine the pressure drop which is required to maintain the
flow at a rate of 10-7 m3 s-1. The effect of kinetic energy due to the change in
velocity in the tube may be neglected. Show the derivation of the final eauation
used in solving this problem.
