The pressure of liquid acting on a container or other body increases at the rate of 1 atmosphere or about 14.7 lbs. per square inch for every increase of 33 feet in depth. So doing the math results in: 400ft./33ft. = 12.121. Multiplying that by 14.7 lbs. per square inch yields about 178 lbs. per square inch at 400 feet deep.

### What is a pressure in a hole 6feet below sea?

pressure acts in all directions.
each 2.31 feet of water = 1 psi
so 6/2.31 = 2.6 psi, don't forget air pressure at surface to add
( 14.7 psi)
so total = 2.6 + 14.7 = 17.3 psi
water pressure represents weight of water of column 1" * 1" * 6
feet high
air pressure represents weight of air of column 1" * 1" * height
to edge of atmosphere from sea level

### What is the water pressure at 5000 feet below sea level?

'Hydrostatic Pressure' is the Term used for 'the force
exerted by a body of fluid at rest. The pressure increases with
increase in depth.
There are two ways to Calculate water (clean water) pressure at
any depth (both yields almost same results):
1. The Hydrostatic pressure of water is 0.433 Psi/ft (Pounds per
square inch Per feet). So at 5000 feet, the pressure is: 0.433
Psi/ft. * 5000 ft = 2165 Psi
another way to go about it is:
2. Water pressure increases at 14.7 psi every 34 feet depth.
Thus Pressure at 5000 ft will be: (5000 ft / 34 ft) * 14.7 psi =
2162 Psi.

### How much pressure is in 328 feet of water?

If it is fresh water, and the surface is at sea level, then the
pressure at the surface is 14.69 psi. As you submerge, then the
pressure from the weight of the water above you is added to the air
pressure above the water. For each foot that you descend, the water
pressure will increase by 0.4331 psi, so at 328 feet deep, the
water pressure is 142.0568 psi. Add the 14.69 psi air pressure to
get 156.7468 psi.
