Hello!
I have a question regarding the application of the bernoulli equation and calculation of the flow through a parallel pipe branch. It's more the basic understanding how the flow will establish.
You can find a sketch attached to follow my explanation.
Let's assume I have a pipe with...
Hi Geniuses...
I joined this group because I have a question I can't answer myself. This is about cars. We're all familiar with classic cars having a grill up front and a space right after it, and then usually a radiator to cool the water/coolant in the engine. The discussion we're having in a...
I am trying to calculate the flow rate of O2 from a known volume 25 in^3. The cylinder will fill up to a maximum pressure of 140 psi in 11.26 seconds. Any help to determine the flow rate will be appreciated. Do I use Bernoulli equation to find the flow rate?
Here is the setup:
Apply Bernoulli Principle to the top (free surface) of the two pitot tubes (1 for static and 2 for dynamic with the points colored in red): $$\frac{p_1}{\rho_w g}=h+\frac{p_2}{\rho_w g}$$
The difference in air pressure would give the following:$$p_1=p_2+h\rho_{air} g$$...
So I'm playing around with some water rockets and I'm trying to figure out how fast the exhaust velocity of the water is. I've had an experimental approach using high fps camera to record and analyse (using tracker) the exhaust velocity. I'm using a 0,5 l soda bottle with 0,085 L ; 0,135 ; L...
Hello everyone,
In Bernoulli's theorem, I understand Potential energy (because of height) and Kinetic energy (because of velocity), but I don't understand pressure [energy]; Is it something like the vibration of molecules and bumping them into each other (in simple words).
Any help or simulation...
I am struggling with what seemed to be a simple problem and any help would be greatly appreciated.
I have to determine the amount of pressure created when air is displaced buy gasoline flowing into a tank.
The gas enters the tank at 10gpm. The entrance has a diameter of 1.5" and the vent has a...

Firstly, I have calculated the pressure at point B.
PB = PA - (0.3m)*(1000kg/m^3)*(9.81m/s^2)
PB = 88057 Pa

Can someone smarter than I, please express p1 and p2 in terms of f, or v and r?
The pump pushes out water at f rate which creates velocity v in the bigger pipe. When the water comes to the restriction velocity increases while flow rate is conserved. Bernouli tells us that the change in...

So, I found a paper relating to a lab report that I've been working on that says that I can get
Qideal=(pi*d^2)/4) √((2ΔP/(ρ(1-D/D')^4 ))
From Bernouli which my book has as:
P1/ρ1+1/2v1^2+gh1=P2/ρ2+(1/2)v2^2+gh2
and Continuity which my book has as:
ρ1A1V1 = ρ2A2V2
I'm able to get kind of in...
I am having a hard time figuring out the step in the equation. For an example, I was given a problem that water flows from the bottom at a velocity of 5.0m/s up to a bucket at (unknown) height. The hose radius is the same so it is not given.
Known:
V_1=5.0m/s
Density p= 1000kg/m^3
Gravity=...

Recently I've been going back in my differential equation book to review some differential equation solving skills, in particular bernouli, ricatti's, and clairaut's equations; simple things enough. However when doing the exercises I have kept running into a "problem" with one question.
