A 12-in. orifice meter (Cv = 0.675) is installed in a vertical segment of a 21-in. -diameter waterline. If the largest flow rate expected is 12.4 ft3/sec, what is the necessary length of a vertical U-tube for the differential (mercury-water) manometer? There is a 9-inch difference between manometer taps, and the flow is in the upward direction.
