Routing the flow from an axial "box" fan

I have a project where I need to generate a certain flow rate to levitate a ping pong ball using the Bernoulli principle. From some rough calculations, I found that it would take about 30 CFM through ...

Increasing air velocity through F1 car diffuser

I am looking into F1 car aerodynamics for a course that I am taking. I understand that because of Bernoulli's law, when the velocity increases, the pressure decreases, which is good for F1 cars if we ...

Pressure variation through reduction (Bernoulli) and pipe wall design

Let's say I have a pipe followed by a reduction and then another smaller diameter pipe continues. Using conservation of mass, the flow through the smaller diameter pipe will have higher velocity. If I ...

Is Bernoulli’s equation applicable for systems with pumps?

Please have patience with me as I have not looked at this sort of theory in many years (I am also very new to StackExchange). A question asks the following: A sloping swimming pool two-thirds full of ...

Can I dismiss wind loads for this solar panel configuration?

I asked this question before in the Physics Stack Exchange, but it was closed because it was considered being about engineering. That is why I am asking it here. I am planning to install some solar ...

Help calculating discharge rate from a reservoir as the water level drops?

I could do with some help calculating the discharge rate from a reservoir and factoring in how that flow will decrease as the head of water decreases. The information I have is: Maximum height of ...

Venturi Duct flow

When water flows through the converging side of a Venturi, why is it that the total head (experimental and calculated) is not constant? Could it be due to losses? Also, why was it that a lot more ...

For a Venturi, I calculated total head theoretically and experimentally. I noticed that the last point along the Venturi has not got the same as the start point total head? Shouldn’t it be the same ...

Calculating Pipe Leak Flow Rate

Just curious and working on some hypothetical problems on my own...I'm currently studying for my PE license. Also, trying my best here with the Latex stuff. Let's say there's a crude oil pipeline and ...

If a gas is pushed through a widening section of a pipe with a piston, will the pressure increase?

Imagine I have a section of pipe that increases in cross-section at some point. If the gas in the pipe before this section is being displaced with a piston, will the gas increase its pressure and ...

Quantifying the reaction force on fixed tubing connected to a peristaltic pump

I am not sure how I should consider the forces due to hydrostatic pressure when calculating the reaction force due to a fluid being pumped through fixed tubing with a peristaltic pump that I am using ...
