C3. An oil of specific gravity 0.85 is flowing through a horizontal venturimeter fitted to a 254 mm diameter pipe at the rate of 92 liters/s and throat diameter is 100 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 779 mm. Calculate (i) the head difference in m of oil, (i) the theoretical discharge in m/s, (ii) the actual discharge in m?/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/mm?, if the entrance pressure gauge shows0.134 N/mm2. (Enter only the values by referring to the unit given. Also, upload the handwritten answers in the link provided) ) the head difference in m of oil (ii) the theoretical discharge in m/s (iii) the actual discharge in m/s
