Question: A polymer solution (density = 1080 kg/m3) is being pumped at a rate of 3200 kg/h through a 60 mm inside diameter pipe. The flow

A polymer solution (density = 1080 kg/m3) is being pumped at a rate of 3200 kg/h through a 60 mm inside diameter pipe. The flow is known to be laminar and the power-law constants for the solution are m = 3 Pa.s (N.s/m2) and n = 0.5.

Estimate the pressure drop over a 20 m length of straight pipe

Estimate the centre-line velocity.
