An oil of specific gravity 0.85 is flowing through a horizontal venturimeter fitted to a 240 mm diameter pipe at the rate of 102 liters/s and throat diameter is 98 mm. The entrance and throat of the venturimeter are connected in the two limbs of a U-tube mercury manometer. The difference in mercury level shows 835 mm. Calculate (i) the head difference in m of oil, (ii) the theoretical discharge in m3/s, (iii) the actual discharge in m3/s, and (iv) the coefficient of discharge of a venturimeter. If instead of a U-tube mercury manometer, the pressure gauges are inserted at the entrance and throat of venturimeter. Find (v) the pressure at the throat in N/mm2, if the entrance pressure gauge shows0.126 N/mm2.
