How to find the water pressure if the area and weight are known?


s (square meter) – the area of the bottom of a vessel filled with water;

F (Newton) is the weight of the water in the vessel.

It is required to determine P (Pascal) – the water pressure at the bottom of the vessel.

To determine the water pressure at the bottom of the vessel, you must use the following formula:

P = ro * g * h, where:

ro = 1000 kg / m3 (kilogram per cubic meter) – water density;

g = 9.8 N / kg (Newton per kilogram) is the acceleration of gravity.

Considering that ro = m / V, and h = V / s, we get:

P = m * g * V / (V * s) = m * g / s = F / s.

Answer: to determine the water pressure, you must use the formula P = F / s.
