This is something that came up at work, as there are four computers running with their air vents placed four to six inches away from the air suction (so that it would suck up the air which was blown out from the air vent fan of a PC.) While this may seem like a good idea on paper (as the suction...
Homework Statement
Consider a fridge with a volume of 120L whose door has 0.8m of height and 0.5m of length. When the door is open there isn't a relevant change in the air quantity inside the fridge. However the temperature increases slightly.
Suppose that when the door is opened, the air...
Dear all,
As I understand the venturi effect, if a flow of water passes through a constriction, its velocity increases and its pressure decreases at the restriction. The decrease in pressure allows a suction force to be produced.
I am trying to use this principle in order to power a vacuum...
hey...I have to develop a suction mechanism for sucking air from a 20 meter high stack to the ground level and at 20lpm outlet flow rate. I don't know the difference between using a suction fan or a pump and which of the 2 would be better .also how to account for all the losses that will be...
This is NOT a "problem", it's a rather a question.
Let's say I've got a vacuum chamber, and I suck the air out of it using a vacuum pump that is capable of doing -200 Kpa. Let's also say that there is a valve on this chamber. After a full vacuum has reached, I open this valve WHILE the pump is...
Is Bernoulli principle the cause of suction truck??
Hello! I’d like to know this question:
When a truck walks to a high speed we see how the road tree leaves are dragged behind it.
I would like to know the real cause of this problem.
I think the air viscosity makes the truck drag a thin...
Say you go into a building where you open one door walk a few feet and open another door. I have noticed that if you open the first door fast the other door obviously opens due to suction? Basically are you doing the work it requires to open two doors or basically the summation of the work of...
I am working on a design for a page turner, and I want to use suction as the means for turning the pages. I was thinking of using a fan or something attached to some tubing with a suction cup on the end which would pick up the page. What kind of fan should I use? I was thinking that this...
Homework Statement
If you have a supply line of water running from one tank to another tank.
And you started to drain the water out of one of the tanks.
Would the downward flow of water create a suction or low pressure in the supply tube?

Hi, I was wondering if anyone can tell me the reason why do we need to suck harder to drink a can drink when 1 straw is out of the drink and 1 straw is in the drink than when we suck the 2 straws while the 2 strws is in the drink?
Sorry For the bad english... I'm from asia you see...
I often use Spectrum Analyzers to probe RF signal powers at different points on multilayered PCBs. These probes have a single conductor (or at least only require a single conductor). Placing the probe on a signal trace on the top exposed surface of the PCBs instantly shows us the RF power at...
