Generally the pressure in the tank air bladder should be 2 psi below the water pressure switch kick in (pump turn on) point. In this example of 48 to 68 Lbs the air bladder pressure should be 46 psi. This pressure should be measured with the tank empty of water, that is to say NO water pressure applied. NEVER over pressurize the air bladder - it would be better to under pressurize if in doubt. Some tank manufacturers may recommend a different PSI differential so check with the tank literature or the manufacturer.

probably as long as you can until you get to a doctor
Water pressure increases with depth. So in a deep lake the bottom of the damn needs to be thicker to accommodate the greater water pressure.
Fish adapt to the pressure.
When applying acute pressure with deep strokes, a hypertonic muscle will release.
There would be more pressure at the bottom of a pitcher of water 35cm deep. +++ To explain, the pressure is a function purely of depth, not volume.
High water pressure.
they use very strong, thick materials or equilize the pressure on the inside to be the same as the outside
In the Heart of the Deep Deep South
true, there are deep in the dermis.
pacinian corpuscle,,,present in hypodermis or deep in the dermis
The air charge in a bladder tank should be 2 PSI below the pressure switch ON setting. In other words if the pressure switch is a 30-50, then the tank air should be 28. -If the pressure switch is the higher 40-60, then the tank air is 38. These tanks are all charged at the top and you can check air pressure there also.
