7. A 150mm diameter horizontal Venturi meter is installed in a 450-mm diameter water main. The deflection of mercury in the differential manometer connected from the inlet to the throat is 375mm (a) Determine the discharge neglecting head lost. (b) Compute the discharge if the head lost from the inlet to the throat is 300mm of water, and (c) what is the meter coefficient?

Connected to an 18-inch water line is a 6-inch horizontal Venturi meter, with a meter coefficient of 0.94. Theobserved average deflection on the differential manometer from the start of the converging cone to the through is15 inches of a fluid with a specific gravity of 8.0. Compute for the head loss between the inlet and the throat.

If the flowing fluid is water and direction is from 1 to 2, determine the

The following data were collected for two verticals in a stream at a gauging station.
