1. A petroleum crude oil having a density of 892 kg/m³ is flowing through the piping arrangement shown in the figure below at a total rate of 1.388 x 10-3 m³/s entering pipe 1. The flow divides equally in the two pipes labeled '3'. The pipes are all Schedule 40. See Appendix M in our textbook for the actual pipe dimensions. 2 11/2-in. pipe 2-in. pipe 3-in. pipe 1/2-in. pipe Calculate the following: a. The mass flow rate in pipe 1, pipe 2 and in each pipe 3. b. The average velocity in pipe 1, pipe 2 and in each pipe 3.
