Repeat Problem 8.12 for an oil temperature of 160°F.

Repeat Problem

An engine crankcase contains SAE 10 motor oil (sg = 0.88). The oil is distributed to other parts of the engine by an oil pump through an 1/8-in steel tube with a wall thickness of 0.032 in. The ease with which the oil is pumped is obviously affected by its viscosity. Compute the Reynolds number for the flow of 0.40 gal/h of the oil at 40°F.
