Calculate the Rate of Flow and Reynolds Number for Oil Flowing in Pipes

Question

A process uses an oil of density 800 kg.m-3 and viscosity 80 mPa.s at a rate of 0.72 m3.h-1. The feed pipe splits into two smaller pipes and both discharge freely into the process. One pipe has an inner diameter of 5.0 cm and length of 20 m while the other has an inner diameter of 2.5 cm and length of 10 m.

1.    Determine the rate of flow in each pipe.
2.    Confirm laminar flow in each pipe by calculating the Reynolds number.


Summary

The question belongs to Mechanical Engineering and the question is about a process where oil flows through a pipe which splits into two. We need to determine the rate of flow for each pipe and confirm laminar flow in each pipe by calculating the Reynolds number. The calculation has been given in the solution in detail.
