About this document
Atmospheric Pressure and Vacuum Levels by rampw14581 is a document available to read on EtoBox.
1) Atmospheric pressure decreases with increasing altitude, lowering the maximum vacuum levels attainable by vacuum pumps. 2) The table provided shows how vacuum gauge readings and maximum vacuum levels decrease as altitude increases, with altitudes over 10,000 feet resulting in vacuum level reductions of over 30%. 3) To account for the effects of lower atmospheric pressure at higher altitudes, the table can be used to correct measured vacuum levels and determine the true maximum vacuum possible at a g
