The water is flowing in the venturi-meter and the area of the broad neck is double of the narrow neck. If the difference in height of the mercury column in the U-tube manometer is 13.6 cm, then find the speed of the water at the broad neck of the venturi meter.

\(\frac{19.04}{\sqrt{30}}\,m/sec\)
3
\(\frac{19.04}{\sqrt{3}}\,m/sec\)
