For the system described in Problem 11.47, and using the tube size found in that problem, compute the expected volume flow rate through the tube if the elevation in the large tank drops to 12.8 m.

Problem 11.47

Figure 11.33 shows a part of a chemical processing system in which propyl alcohol at 25°C is taken from the bottom of a large tank and transferred by gravity to another part of the system. The length between the two tanks is 7.0 m. A filter is installed in the line and is known to have a resistance coefficient K of 8.5 based on the pipe velocity head. Drawn stainless steel tubing is to be used. Specify the standard size of tubing from Appendix G.2 that would allow a volume flow rate of 150 L/min.
