Water is lifted from a large open vessel using a pipe with an internal diam-eter of 200 mm, which extends to a depth of 10 m in which compressed air is admitted forming small bubbles forming a two- phase mixture with a com-bined average specific gravity of 0.8 shown in Figure 1.10. If the pipe extends to an elevation of 2 m above the surface of the water, determine the rate of flow of water.
