In the figure below, the water surface elevation of the upper tank is 2,862 feet and the water surface elevation of the lower tank is 2,246 feet. Both tanks are open to the atmosphere. The total head loss from the upper storage tank to the lower tank is 2.8 feet. There is a differential manometer connecting the blue pipe, and the green pipe. There is no head-loss across the manometer. The liquid used for the differential manometer has a specific gravity of 2.8, and the reading, Rm is 17-inches. D₁ = 24-inch and D₂ = 20-inch. What is the flow in between the two tanks?
