A Mercury Water Differential Manometer R 740mm Is Connected From The 100 Mm Diam

A mercury-water differential manometer, R’=740mm, is connected from the 100-mm-diameter suction pipe to the 80-mm-diameter discharge pipe of pump, as shown in the Figure. The centerline of the suction pipe is 330mm below the discharge pipe. For Q=3.42m3/ min of water, calculate the head developed by the pump. (ans: 13.19m)
