Entrance Length in Pipe Flow: ConcepTest and Example Problem

Try to answer this ConcepTest and solve this example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. By the end of this module, you should be able to answer these on your own. Answers will be given later in this module.

A practice problem for a Entrance Length in Pipe Flowself study module.
Example Problem 1

Water enters a 4-in. diameter piping system from a reservoir with a volumetric flow rate of 50 gal/min. Determine whether the flow is laminar or turbulent if during the winter the water temperature is 45°F and if it reaches 65°F during the summer. What is the length of pipe necessary to reach fully developed flow?
