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.

Carbon dioxide is being pumped through a smooth pipe at the rate of 3×10-4 kmol/sec for a distance of 2000 m. Ifthe line is isothermal at 323.15 K and the pressure at the entry point is 750 ×103 Pa and at the exit point is 430×103 Pa, what diameter should the pipe has to ensure that the CO2 will be delivered to the end point with the pressure drop experienced.
