Flow vs differential pressure relationship

WebWhen a differential pressure is applied to one side of a soap film, the newly born soap bubble adopts a different shape. Due to the surface tension, the soap bubble still tends to minimise its surface area, but this time under volume constraint. The relationship between the differential pressure and the shape of the soap bubble was established circa 1800 … WebOct 5, 2024 · Flow is the ability of an air compressor to continuously perform a task. In the U.S., flow is typically measured in cubic feet per minute (cfm) at a specific pressure. …
