Given:
A hose has a diameter of 2 cm and the speed of water is 0.1m/s. Eventually, the pipe tapers to a diameter of 1cm.
To find:
Speed of water in the tapered portion ?
Calculation:
In these kind of questions, it is best to use EQUATION OF CONTINUITY:
Initial radius = d/2 = 2/2 = 1 cm.
Final radius = d/2 = 1/2 = 0.5 cm.
So, applying Equation of Continuity:
So velocity of tapered part is 0.4 m/s.
So velocity of tapered part is 0.4 m/s.
