What is the psi at the bottom of a 800 gallon tank of water?

Answer 1

Take the water level of the tank if feet.

Multiply that by 0.433 and that will give you psi at the bottom of the tank.

One foot of water = 0.433 pounds per square inch

Assuming the tank is at atmospheric pressure.

Answer 2

The psi depends on the depth of the water. If it is a 2 foot tall tank the bottom will be at half the pressure it is for a 4 foot tall tank. The volume has nothing to do with that pressure.

Given the tank's height and the rule that 30 feet deep = 14.7 psi you can do the arithmetic when you have the depth.

Answer 3

Ft Of Water To Psi

Answer 4

The pressure at the bottom depends only on the depth of the water, not the capacity of the tank. For every foot depth, the pressure increases by 62.4lb/sq.ft., because water weighs that much per cubic foot. Just multiply that number by the water depth in feet. If you need it in lb/sq.in., divide your answer by 144sq.in./sq.ft.

Answer 5

The rule of thumb for water pressure for firefighting is 4 p.s.i. per 10-foot story or 1 p.s.i. for 2.5 feet of rise. This slightly underestimates the pressure. Ir is really closer to 1 p.s.i. per 2.3 feet of rise, depending on how close an answer you need.

Or to get an accurate answer, divide the weight of one cubic foot of water by 144 to get p.s.i. per foot of depth/rise and multiply that by the depth in feet.

Answer 6

Wrong info. It doesn't have anything to do wih he amount of water in the tank.. It is dependent only on the depth of the water.

Answer 7

Pressure has to do with depth rather than volume. Not enough info to answer.

Answer 8

dimensions of the tank?

Answer 9

Not much if its empty. And it depends what is in it.
