A water cleanup is stripping vinyl chloride from contaminated ground water at 25C and 850 mm Hg using a countercurrent, staged stripper. The feed is 5.0 ppm (molar) vinyl chloride. An outlet water that contains 0.1 ppm (molar) vinyl chloride is required. The inlet air used for stripping is pure. For a base liquid flow rate of L = 1.0 kmol/h, determine the following: a. The minimum gas flow rate Gmin in kmol/h.

Explain the triangle relation, I don't get it.
