Water flows through a pipe that has a variable diameter as shown. At point X, the diameter of a pipe is 3cm and water flows with a speed 10.8 m/s. The diameter of the pipe at point Y is 6 cm. What is the speed of the water at point Y?

The most crucial scientific concept is measurement. Base or physical fundamental units are used to measure a wide range of measurable quantities. One such measurable quantity is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance. Let's explore speed in-depth in this session.

If an object travels the same distance in the same amount of time, it is said to be moving at uniform speed. When an object travels a different distance at equal intervals of time, it is said to be moving at variable speed.

Since water flows through the diameter 3cm at speed 10.8m/s

It enters larger pipe of diameter 6cm

velocity of large pipe = velocity of small pipe (area of large pipe/ area of large pipe)

V = 10.8(36/9)

= 43.2m/s

the speed of the water at point Y = 43.2m/s
