A venturimeter (throat diameter = 10.5 cm) is fitted to a water pipe line (internal diameter = 21.0 cm) in order to monitor flow rate. The improve accuracy of measurement, pressure difference across the venturimeter is measured with the help of an inclined tube manometer, the angle of inclination being 300 (see figure below). For manometer reading of 9.5 cm of mercury, find the flow rate. Discharge coefficient of venture is 0.984.
