Why canals are constructed in 'V' shape? Explain. |
| Answer» SOLUTION :The water in canals flow in the form of layers. When the canals are constructed in "V" shape, the AREA of contact between the layers decreases from TOP to bottom of the canal. The viscous force is directly proportional to the area of contact between the layers. Because of this REASON the viscous force between the layers decreases and the water FLOWS freely along the canal. | |
