What is the pressure of water in a 1000 gallon tank?

Question

In psi what is the pressure exerted on the walls of a 1000 gallon tank of water?

Answer 1

Max pressure (in psi) exerted on the tank walls is equal to:

0.434 x [Water Depth in Feet]

This is true for any volume of water

Assumption: tank is open to the atmosphere

The max pressure occurs at the lowest point of the tank.

Answer 2

With 1000 gallons you'd have about 4 or 5 psi near the bottom of the tank.

Answer 3

Sorry, we need more info. PSI is lbs per square inch and we need a surface area or volume of the tank to help you out. If you know what it is just do the following

(density of water*volume of water you have)/(surface area of tank)

This is for static/still water. You can also use pressure=density*gravity*height of water if the container is open

Answer 4

A lot of wrong answers.

You need the shape and size of the tank, or (and this is all you really need) the height of the water.

1 inch of water is 0.036 psi

12 inches (1 ft) of water is 0.434 psi

2 ft of water is 0.867 psi

3 ft of water is 1.300 psi

4 ft of water is 1.734 psi

5 ft of water is 2.168 psi

10 ft of water is 4.34 psi

20 ft of water is 8.67 psi
