what is the pressure at 25000 feet underwater

According to the search results, there are different ways to calculate the pressure at a certain depth underwater. One way is to use the hydrostatic pressure equation, which states that the pressure, P, of a fluid at depth depends only on the density, ρ, the acceleration of gravity, g, and the depth or height of the fluid column, h. The formula is P = ρgh. Another way is to use the rule of thumb that the pressure increases about one atmosphere for every 10 meters of water depth. Using this rule, the pressure at 25,000 feet, which is approximately 7,620 meters, would be about 762 atmospheres or 11,124 pounds per square inch. Its important to note that the actual pressure may vary depending on factors such as the density of the water and the altitude of the location.
