the bottom of the tank?

Look up hydrostatic pressure and learn something.
or cheat....
Imagine a block of water 1 metre square and 4 metres high. The density of water is near enough 1000 kilograms per cubic metre so the weight of the four cubic metres of water is 4000 kg times g (gravity) which is 39200 newtons. This force is exerted over 1 metre square, so the pressure produced by 4 metre depth of water is 39200 pascals.

Pressure at bottom=4*1000*9.81Pa
Pressure at Middle=4/2*1000*9.81Pa
Pressure at Top of water= 0 Ans.

There are a few answers provided by a number of people. Pressure at any point can be measured in gauge pressure units (psig) or absolute pressure unit (psia). When using English pressure units.
Psia = psig + 14.696 lb/in. sq.
Pressure is heighest at the bottom of the tank
P = water density X Height of water coulmn above that point + atomspheric pressure ( assuming tank top is open to atomsphere )
Pressure is lowest at the top ( at the top free surface of water) of the tank.
You select units of measurement according to your own choice.

the pressure is equal to the pressure due to the height of the water, plus the pressure due to atmosphere or pressure of the space above the tank. If the tank is at atmospheric pressure at sea level you would add 14.7 psia to the weight of the water. Below is a link to a coversion table.

The rigidity would be 4 meters of water rigidity or 4000mm of water rigidity or 157 inches of water rigidity or 11.6 inches of mercury rigidity or 5,68PSI because a million meter of water rigidity = 9.80 one kilopascals rigidity Then 4(meters)X 9.80 one=... 39.24

Pressure is strictly a function of the density of the fluid times its height:
P = density * height.

Pressure in millibars at any location:
1013.25 millibars + x*98.0666 millibars where x is in meters
at 4 meters
1405.5162 millibars
