Question: After the press has run for some time, the lubricating oil described in Problem 8.19 heats to 212F. Compute the Reynolds number for the oil

After the press has run for some time, the lubricating oil described in Problem 8.19 heats to 212°F. Compute the Reynolds number for the oil flow at this temperature. Discuss the possible operating difficulty as the oil heats up.

In Problem

The lubrication system for a punch press delivers 1.65 gal/min of a light lubricating oil (see Appendix C) through 5/16-in steel tubes having a wall thickness of 0.049 in. Shortly after the press is started, the oil temperature is 104°F. Compute the Reynolds number for the oil flow.
