Temperature affects the velocity of water by changing its density. Colder water is more dense and therefore flows slower, while warmer water is less dense and flows faster.
Yes, the shape of the container can affect the velocity of water. A narrow container will cause water to flow faster, while a wider container will cause water to flow slower. This is due to the surface area of the container and how it affects friction and resistance.
No, adding salt to water will not increase its velocity. While the density of saltwater is higher than freshwater, the effect is minimal and is not enough to significantly increase the velocity of water.
Gravity plays a crucial role in the velocity of water. The force of gravity pulls water downward, causing it to flow and increase in velocity. The steeper the incline, the faster the water will flow due to the increased force of gravity.
To increase the velocity of water in a pipe, the diameter of the pipe can be decreased, resulting in a narrower and faster flow of water. Additionally, reducing any friction or resistance in the pipe can also increase the velocity. This can be done by using smoother materials for the pipe or by reducing bends and turns in the pipe.
