Determine hydrostatic pressure of pool

Question

How do you measure the hydrostatic pressure that groundwater puts on the bottom and surrounding floor of a pool. If ground water is only a meter from the surface(ground level). Pool dimensions 16.5‘ by 33’. Depth of pool is 3.3’ for half the pool, other half the pool is 6.6’ depth.

Answer 1

Hydrostatic pressure = P = r * g * h 

r (rho) is the density of the fluid,

g is the acceleration of gravity

h is the height of the fluid above the object 

At any point in the pool the density of water and the value of g are the same. So you realize that hydrostatic pressure in the pool only depends on the depth of the point you are measuring.

Also, remember that hydrostatic pressure is equal in all directions at that point. So the bottom of the pool will experience pressure from the column of water directly above it.

3.3 feet is 1 meter.

Issue here is that the pool has a shallow and a deep end. It's split in the middle. So half the pool has pressure of (1000 Kg/m3) * (9.8 m/s2)*(1) = 9800 Kg/m2/s2

and twice that in the area where the depth is 6.6 feet
