PROBLEM NO.1 A $150\mathrm{mm}$ 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 $375\mathrm{mm}$. (a) Determine the discharge neglecting head lost. (b) Compute the discharge if the head lost from the inlit to the throat is $300\mathrm{mm}$ of water, and (c) what is the meter coefficient?
