A Venturimeter having a throat diameter d2 of 100 mm is fitted into a pipeline which has a diameter d1 of 250 mm through which oil of specific gravity 0.9 is flowing. The pressure difference between the entry and throat tappings is measured by a U-tube manometer, containing mercury of specific gravity 13.6, and the connections are filled with the oil flowing in the pipeline. If the difference of level indicated by the mercury in the U-tube is 0.63 m, calculate the theoretical volume rate of flow through the meter.

ANSWER: Q = 0.105 m³/s
A Venturimeter having a throat diameter d2 of 100 mm is fitted into a pipeline which has a diameter d1 of 250
mm through which oil of specific gravity 0.9 is flowing. The pressure difference between the entry and throat
tappings is measured by a U-tube manometer, containing mercury of specific gravity 13.6, and the connections
are filled with the oil flowing in the pipeline. If the difference of level indicated by the mercury in the U-tube
is 0.63 m, calculate the theoretical volume rate of flow through the meter.
