Repeat Problem 9.10 if the oil is at 110°C but with the same flow rate. Discuss the differences in the velocity profile.

Repeat Problem

A large pipeline with a 1.200-m inside diameter carries oil similar to SAE 10 at 40°C (sg = 0.8). Compute the volume flow rate required to produce a Reynolds number of 3.60 × 10⁴. Then, if the pipe is clean steel, compute several points of the velocity profile and plot the data in a manner similar to that shown in Fig. 9.7.
