Multipipe Systems: ConcepTest and Example Problem

Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.

Example Problem 1

An incompressible fluid with a density of 0.00209 slugs/ft3 flows from a tank at 0.5 psi through a 20 ft long pipe of 1 inch diameterĀ  and then through a pipeĀ  0.5 in diameter also 20 feet long. If the friction factor for both pipes is 0.015, what is the flowrate? Assume the pipe exits into the atmosphere and neglect minor losses.
