The speed of the gas must increase. Also, depending on the geometry
of the transition, it's comparatively difficult to maintain laminar flow, and
there's typically considerable turbulence there and for some distance after.
When a steadily flowing gas flows from a larger diameter pipe to a smaller diameter pipe the speed of gas is decreased and pressure become increased and the spacing between the streamlines less and the streamlines come very close to each other.
When steadily flowing water transitions from a larger diameter pipe to a smaller diameter pipe, its velocity increases due to the principle of continuity, which states that the flow rate must remain constant. According to Bernoulli's principle, as the velocity of the fluid increases, its pressure decreases. Therefore, the pressure in the smaller diameter pipe is lower than in the larger one.
It is not. It is the other way round, a stream or smaller river flowing into a larger one.
There are two rivers flowing through Omsk Russia. They are the Om' river (the smaller one) and the larger one named the Irtysh (Irtish) river
The smaller stream is a tributary of a larger stream, river or lake.
A tributary is a small stream or body of water that flows into a larger body of water. Note that a tributary could also be a river, for example, the Missouri and Ohio rivers flow into the Mississippi river.a tributary (correct spelling) is basically a smaller river that flows into a larger river.
tributary
The smaller stream is the tributary of the larger river.
A small freshwater river or stream flowing into a larger river is called a tributary or feeder river. A tributary is a stream or river that flows into a mainstem (or parent) river or a lake. For example, a tributary can be a creek that flows into a river. Or it can be a small river that flows into a larger river. A tributary does not flow directly into a sea or ocean. Some large rivers can have up to 100 tributaries. The spot where the smaller and larger river meet is called a "confluence". In contrast, a body of water that branches off and flows away from the main river is called a distributary.
Blood coming out of the capillaries passes into vessels of increasing diameter as it flows back toward the heart. It is usually deoxygenated.
No - the smaller river is a 'tributary' of the larger one.
A smaller stream of freshwater that flows into a larger stream is called a "tributary." Tributaries contribute to the flow and water volume of the main river or stream they feed into, and they play an important role in the watershed ecosystem.
