The narrowing of the stream is due to surface tension, which causes water molecules to cling together along the edges of the stream. As the water falls, gravity pulls it downward, forcing the stream to stretch and narrow. This effect is more noticeable with slower flow rates.
The water coming out of a faucet becomes narrower as it descends to the law of continuity. A1 x v1 = A2 x v2, or the product of the cross section of the substance in flow at one point and its speed must be equal to the product of the cross section and speed at the next point. In the case of water falling, it is subjected to the acceleration of gravity. To accommodate the increase in speed the cross section of water flowing to the next point will decrease until the water reaches terminal velocity.
It is because velocity is inversely proportional to the cross-sectional area. As the water runs down from the faucet it changes velocity because of the pull of gravity, hence the liquid will be narrower as it falls down the ground.
An increase in stream velocity can be due to factors such as a steeper gradient, higher discharge, narrower channel width, or decreased channel roughness. These factors can contribute to higher flow velocities in rivers or streams.
The narrow part above the bulb is known as the "throat" of the saxophone. It helps to focus and funnel the air stream coming from the player's mouth towards the reed. This design enhances the control and direction of the air, improving the instrument's responsiveness and tone production.

As water flows from a faucet, gravity pulls it downward, causing the stream to accelerate. Due to the conservation of mass, as the water falls and spreads out, its velocity increases, leading to a decrease in cross-sectional area, resulting in a narrower stream. This phenomenon is also influenced by surface tension, which pulls the water molecules together, further contributing to the narrowing effect.
It is because velocity is inversely proportional to the cross-sectional area. As the water runs down from the faucet it changes velocity because of the pull of gravity, hence the liquid will be narrower as it falls down the ground.
The velocity of the water in a stream increases when the stream gets narrower or shallower (or both).
As the water flows from the faucet, it is influenced by gravity, creating a continuous stream. The pressure from the plumbing system pushes the water out, and as it exits the faucet, surface tension causes the water to maintain a cohesive shape. Eventually, the stream may break into droplets due to factors like air resistance and the force of gravity pulling it down. This process can result in varying flow patterns depending on the faucet's design and the water pressure.
Stream velocity is dependent of four things. They are, the flow type, the gradient, the channel shape, and the discharge of the stream. Streams will flow faster in narrow channels on steeper grades.
Stoppage down stream
When water flows from a faucet, it is propelled by the pressure in the plumbing system, which pushes it through the pipes. As it exits the faucet, the stream takes shape due to surface tension, forming a cohesive column of liquid. Gravity pulls the water downward, causing it to fall freely until it reaches a sink or basin. The flow can also be affected by factors such as the faucet's design and the water pressure.
A stream that is longer and wider is usually considered a BROOK or a RIVER.

A stream lengthens when downcutting occurs, downcutting is when the bottom of the stream is slowly dug out, this process will dig at the end of the river until it becomes part of the river.
