A pumping station wet well operates between 540- and 550-ft elevation. The pump curve is deϐined by the following points: 80 ft at zero ϐlow, 78 ft at 200 gpm, 65 ft at 800 gpm, and 50 ft at 1200 gpm. The pump discharge contains an equivalent of 50 ft of 6-in. pipe.

Fundamental of fluid flow: A venturi meter with a throat diameter of 6 cm is fitted in a horizontal pipeline of 12 cm diameter with oil of specific gravity 0.88 flowing from left to the right. The difference in level in the two limbs of a mercury manometer connected to the tapping points read 12 cm and the connecting pipes are filled with the same oil. (a) If two pressure gauges are fitted at tapping points, one at the throat and the other in the inlet. Determine the difference between the 2 gage pressure readings in kPa. (b) Determine the flow in m^3/s neglecting head losses.
