During my studies, I found a Physics problem.
I came across a paragraph talking about hydraulics in aviation mechanics. This was mentioning the relationship between a [b] hydraulic[/b] Governor (devices that regulates propeller speed and angle, in this scenario) and the actual propellers. The problem? It was telling me that it's impractical to have an hydraulic governor away from the propellers to the rear of the engine [b] because of the distance of oil passages being greater in length between the two.[/b] My brain short circuited as to [i]why is that?![/i]
Pascale's law states pressure of a confined incompressible fluid (like oil and water) [b]at rest[/b] will apply equal pressure in all directions no matter the length of the pipe, conduit, passageway, ect...
So why is it impractical when distance doesn't matter in Pascal's Law?
My mother was at the table listening and understood the concept, while I was trying to figure this out. But I think I lost her when I did because the answer was, [b]they didn't specify if the fluid was flowing or at rest[/b] (Which I should've known better since I've worked on cars for so long knowing that oil circulates through the engine, but my brain thought that the fluid would be static like the hydraulic fluid in your car's shock/absorbers suspension).
If a fluid is [b]flowing[/b] in a confined space, as is the case between the governor and propellers, then the greater the distance the oil has to travel it WILL LOSE pressure due to friction in the oil passage ways. That's why it's impractical.
And that's also when my mom just up and left without saying a word. I mean, I currently DO not have a degree in physics or anything really so I thought that was pretty cool to learn about and figure out. Guess I just need to be with my people on this one. 馃ズ
