For the flow of 12.9 L/min of water at 75C in a plastic pipe, 16 mm OD × 1.5 mm wall, compute the expected maximum velocity of flow.
A large pipeline with a 1.200-m inside diameter carries oil similar to SAE 10 at 40C (s g=0.8). Compute the volume flow rate required to produce a Reynolds number of 3.60*10^4. Then, if the pipe is clean steel, compute several points of the velocity profile and plot the data.
