Buoyancy Pressure under tank
Buoyancy Pressure under tank
(OP)
Will someone tell me whether the buoyancy force increase with depth. I have a precast concrete tank where top of concrete is 3' below surface and the water table is at grade. the Tank is 9 feet deep and covers an area of 10'x80'. I calculate the buoyancy (uplift force) as 10'x80'x9'x62.4pcf=449280lbs. Is this correct? That is the weight of displaced water mass. The fact that the top of tank is 3 feet under the water table doesn't play a role here. THe buoyancy is not dependent on the depth?? So regardless hhow deep in water the tank is buried the buoyancy force is the same. Can someone confirm or challenge this please; I must have failed My physics 101.
thanks

Don't forget that the uplift force is resisted or partially resisted by the weight of the structure.
