Water is flowing through a venturimeter having a diameter of 0.25 m at the entrance (Station 1) and 0.125 m at the throat (Station 2) as shown in the figure. A mercury manometer measures the piezometric head difference between Stations 1 and 2 as 1.3505 m. The loss of head between these two stations, is 1/7 times the velocity head at the Station 2. Assume the acceleration due to gravity to be 10 m/s2. The velocity of water at the throat is ____ m/s. • • 1 2 diameter 0.125 m diameter 0.25m Mercury Manometer XE (GATE 2014)
