What is 1500 feet of water converted to psi?

If we have six (6) feet of water, that will convert to about 2.6 psi (pounds per square inch).


What is the PSI at 400 feet below sea level?

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 are the units used when measuring the depth of water?

Depth of Water Measurement.Water is measured by many strategies such as a sounding line, depth guages (based on pressure) and by sonar messurement. Before the moden age, sailors would throw lead weighted lines into the water. These were marked off in six foot increment (fathoms) and would call out the depth, or int he old English phrase - sound off, hence the term sounding the depth.Submarines brought a new requirement for depth measurement, the need to know how deep the boat was in the water. Since water has weight, there is a direct correllation to the depth of the water and the pressure outside the submarine. Most depth guages are calibated in feet or meters of seawater as most submarines operate in salt water, which is heavier than fresh (non-salty) water.Modern electronics has now allowed sophisticated measuring devices to bounce waves off the bottom and determine exaclty the depth of water that a boat is in. This is now used on many pleasure and fishing boats as a necessary navigation aid.Satellite detection of water depth is now used to determine changes in fresh water reserves on continents and to determine the changes in climates and geography.
