Velocity at a reservoir (Bernoulli's equation)

AI Thread Summary
The discussion revolves around the application of Bernoulli's equation in the context of a reservoir. It highlights that the velocity at a large reservoir is considered negligible due to its vast size, which means that the flow velocity is minimal compared to other points in the system. The continuity principle, which relates the flow rates and velocities in different areas of a fluid system, clarifies this concept. The user initially struggled with understanding the significance of negligible velocity but later recalled the continuity principle, resolving their confusion. This emphasizes the importance of both Bernoulli's equation and the continuity principle in fluid dynamics.

TL;DR Summary
Velocity at a reservoir
Hi there,

I am solving a problem which requires me to use Bernoulli's equation and I have across a hint that says that "velocity at the reservoir is negligible because the reservoir is large" and I do not understand what that means exactly. How is velocity at a reservoir negligible?

Nevermind, i had forgotten about the continuity principle.
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
