Question

Sink drains often have a device such as that shown in Figure 12.28 to help speed the flow of water. How does this work?

Short answer

The device helps to increase the flow rate of water.

Step-by-step solution

Speed

The rate at which the location of an object changes in any direction. The ratio of distance traveled to the time it took to travel that distance is known as speed.

Explanation

The diagram of the device is shown below:

The fig 12.28

These types of devices divide the flow of water into different blocks. The division of blocks reduces the area of the flow and increases the speed of flow of water.

Conclusion

Those devices are used in sink pipes. The division in the area of flow reduces the area and the flow rate of water increases.
