The hydrostatic pressure, which is counted with (density*gravitational acceleration*height) is about 1000kg/m3*9.8m/s2*90m = 882 000Pa now you add the pressure ontop of the water, which normally is the atmospheric pressure (~100000Pa) and you get 982000Pa.
Also, do your own homework :3
Just under 60 psi at 30m
The pressure at a depth of 10 meters underwater is about 2 atmospheres, which is equivalent to around 1 atmosphere of pressure at the surface plus an additional atmosphere for every 10 meters of depth. This increased pressure is due to the weight of the water above pushing down on you.
The pressure at a depth of 5 meters under water is approximately 0.5 atmospheres, which is equivalent to 49 kilopascals. This pressure is caused by the weight of the water above pushing down on the water at that depth.
Water pressure increases by approximately 1 bar for every 10 meters of depth in freshwater. At a depth of 10 meters, the water pressure would be about 1 bar, in addition to the atmospheric pressure at the surface, which is roughly 1 bar as well. Therefore, the total pressure at 10 meters depth would be about 2 bars.
406 meters / 1,332.02 feet of water depth has a pressure of about 39.3 atmospheres or 577.6 psi.
At one atmosphere of pressure, which is approximately the pressure at sea level, the depth in fresh water is about 10.3 meters (or 33.9 feet). This is because the pressure increases by about 0.1 MPa (megapascals) for every 10 meters of water depth. Therefore, at 10.3 meters, the pressure from the water column adds an additional atmosphere to the surface pressure.
At 30 meters depth in salt water, a diver will experience a pressure of approximately 4 atmospheres or 4 times the pressure at the surface. This is because water exerts 1 atmosphere of pressure for every 10 meters of depth.
The water pressure at a depth of 30 meters can be calculated using the formula P = ρgh, where P is the pressure, ρ is the density of water, g is the acceleration due to gravity, and h is the depth. Assuming standard values, the water pressure at a depth of 30 meters is approximately 294,300 Pascals.
The recommended water pressure is 0.5 to 1 bar
Yes, 2 ATM is equivalent to the water pressure at a depth of approximately 20 meters underwater. This is because each additional 10 meters of depth adds around 1 ATM of pressure.
Water pressure is greatest at a depth of about 10 meters below the surface, where the pressure is equivalent to the weight of a column of water 10 meters tall. This pressure is greater than the pressure exerted on an iceberg floating at the surface, as the weight of the water column increases with depth.
Every 10 meters, the pressure will increase by one atmosphere. That is about 33 feet.
