15.78 psi
If we have six (6) feet of water, that will convert to about 2.6 psi (pounds per square inch).
Standard atmospheric pressure at sea level is about 14.7 PSI. So, then what is the pressure at about 5,645 feet below the surface of the earth?
14.7 PSI at sea level and decreasing one PSI per 2343 feet of altitude would be 14.41660264618 PSI at 664 feet above sea level this also has to be adjusted for temp as well
14.7 psi = sea level. 15.2 psi = 1671 ft below sea level
At 99 feet below the surface, the total pressure on a diver can be calculated using the formula: total pressure = atmospheric pressure + (depth in feet × 0.433 psi/ft). The atmospheric pressure at sea level is approximately 14.7 psi. Thus, the total pressure at 99 feet is about 14.7 psi + (99 ft × 0.433 psi/ft) = approximately 14.7 psi + 42.8 psi = 57.5 psi. Therefore, the total pressure on a diver at that depth is approximately 57.5 psi.
The recommended psi level for effectively cleaning siding is between 1500 and 2500 pounds per square inch (psi).
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.
170 psi
The pressure of water increases about 0.445 psi per foot of depth. If we "zero" our meter so we have "no" pressure at the surface (ignoring the normal 14.7 psi of air pressure at sea level), at 18 feet we will have 0.445 psi/ft times 18 feet, which is 8.01 psi, or right at about 8 psi.
The pressure at 1200 feet below sea level is approximately 517.2 pounds per square inch (psi). This value is calculated using the formula: pressure = depth × density of seawater × acceleration due to gravity.
At 1 mile below sea level, the pressure in pounds per square inch (psi) would be approximately 2,227 psi. This represents the increase in pressure due to the weight of the water column above at that depth.
