How to know water pressure in a tank?

Hello guys, how to calculate water pressure in a tank? If we have a water tank having 10 liters water in it then what will be pressure on the bottom of the tank? What can be standard formula to calculate water pressure in this case & similar cases?

Any idea?

Thank you!

I found p = pa + Sy

But this is the general formula, Is there any other formula to calculate pressure of a water tank?

waiting for your reply...
