its can be a restriction in liquide line
I am not sure if they are proportional, but they are inversely related. High pressure makes a low vacuum, and low pressure makes a high vacuum.
Low pressure
The ultimate objective of a manufactured vacuum is zero pressure.The better the vacuum, the closer the pressure is to zero.
The atmospheric pressure on the moon is nearly zero (effectively vacuum).
High Vacuum was created in 1957.
oil gage pressure immediately goes high
a vacuum is simply an empty or almost empty space. The forces that are apparent with vacuums are due to a pressure imbalance between the inside of the vacuum (low pressure) and the outside of the vacuum (high pressure) causing particles to want to migrate to areas of lower pressure. The effect of this pressure difference is often refered to as a vacuum force
High Vacuum has 192 pages.
On a manifold gauge set, there are two gauges. The gauge encased in red measures pressure on the high pressure (discharge) side. That's the "high side gauge". The other will be incased in blue, and measures vacuum pressure on the low side.
High pressure. A hot air balloon has a maximum altitude, where it has only just enough lift to keep it there, because there is very little difference in density between hot (near) vacuum and cold (near) vacuum.
A high pressure systems has a high pressure center.
because inter molecular distance is very small at high pressure and it goes on decreasing with the increase in pressure.
