The pressure only depends on the height of water above the outlet. The width or
height of the tank make no difference. (The tank may very well be 16-ft tall, but if
the tank is empty, then the pressure at the drain is zero.)
If the water is 16-ft high above the outlet, then the pressure is "16-ft of water".
That pressure is also equivalent to:
-- 998.82 pounds per square foot
-- 0.499 ton per square foot
-- 6.94 pounds per square inch
-- 0.472 atmosphere
-- 14.12 inches of Mercury
-- 35.87 centimeters of mercury
-- 47.82 kilo-Pascals
At 300 feet of water depth the pressure is about 130 psi
The pressure is 394 atm.
50 feet of water is about 1.475 atmospheres.
Water pressure at a depth of about 44 feet is about 20psi
water for example.absolute pressure; gauge pressure; atmospheric pressure
The water pressure when one turns on the hot water is lacking because the water is coming from one's water heater, which is at the same level as the faucet, whereas the pressure from the cold valve is coming directly from one's town's water tower, which is at a much greater elevation. Also, the water heater tank is only a few feet high, whereas the water holding cell in a water tower is several feet high. The potential energy of the water tower far exceeds that of one's hot water heater, thus the cold water flows out of the faucet with much more pressure.
At 5,400 feet of water depth the pressure is about 2,341.1 psi
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.
The 260 feet of water: at that depth, there is the weight of the water and the atmosphere on top of it.
172.3 feet
About 240 psi at 500 feet of depth.
20 bar of pressure is about 200 ft.
