A complete vacuum is created in the absence of matter, especially in gaseous form. The phenomenon of suction generally associated with a vacuum results from a pressure gradient. Since P=nRT/V and there are more moles of gas outside of the vacuum there is also a greater pressure outside of the vacuum.
what i found out was if your vacuum doesn't have suction you need to make sure you have all the air out of the hose that is attached to you vacuum.
If you have a dedicated suction for the vacuum hose (illegal in Australia) then you close the skimmer to increase suction.
A suction Cup will trap air behind itself which causes a partial vacuum. The negative pressure of trapped air or water causes it to keep in contact with the surface it is against.
The procedure is also called dilation and evacuation (D and E), suction dilation, vacuum curettage, or suction curettage
The procedure is also called dilation and evacuation (D and E), suction dilation, vacuum curettage, or vacuum aspiration
a vacuum cleaner uses air to create suction. in a vacuum there is no air. Therefore, the aswer is NO.
A Vacuum Saction machine uses Alternate Current AC
The length of the suction hose is around 2 feet, with an additional extender where the hose can extend up to 3 feet. with the Canister Vacuum.
To suction the dirt out of your carpet
No, a suction cup works by forcing air out of the space between it and the surface it's on. No air = no suction.
