Ultrahigh vacuum Wikipedia
Ultrahigh vacuum is the vacuum regime characterised by pressures lower than about 10−7 pascal or 100 nanopascals. UHV conditions are created by pumping the gas out of a UHV chamber. At these low pressures the mean free path of a gas molecule is greater than approximately 40 km, so the gas is in free molecular flow, and gas molecules will collide with the chamber walls many times before colliding with .

Understanding and avoiding pump cavitation | Flow Control ...
In the case of suction cavitation, lowpressure or highvacuum conditions "starve" the pump of incoming liquid, resulting in low flow. Bubbles form near the eye of the impeller, and as they move toward the discharge side of the pump, the bubbles compress into liquid and implode against the impeller's edge.

Convert From Vacuum to Electric Fuel Pump
Apr 15, 2018· I have a Husqvarna 24V54 (YTH2454) (Intek VTwin) that always takes forever to start after sitting for a few days. Put a new pulse pump on it but didn't help. So I've decided to put a universal, low pressure, 12v gas pump on it. Problem is, I haven't any idea which of those pumps on ebay would work. Anyone here made such a conversion? Would a 24 psi pump work okay?
