Cubic metres of water to Bar pressure

[brimal]

I am trying to find out the Bar pressure of water at a given point.
I have a tank of water 113cm x 55cm x 43cm (0.27 cu m) which has an outlet at the bottom which is 2 metres above my shower unit. Could someone pse tell me what the Bar pressure at the outlet would be? Is this possible to calculate?

Do you want the pressure at the bottom of the tank, or does a pipe feed the shower, the pipe is full of water, and you want pressure at the shower head? In one case the total head is 2 m, in the other case 0.43 m (I am guessing which dimension is height)

Scuba divers use a rule of thumb that 10 m is approximately 1 atm or 1 bar (they are very close). So the pressure at the shower head is about 0.2 bar.

If you want to refine this, the pressure of a column of liquid is
P = rho*g*h, where rho is density, g is accel. due to gravity, and h is height. If rho is kg/m^3, and h is in m, the pressure will be in Pa, 10^5 Pa = 1 bar. g is 9.8 m/s^2, if it were 10, you'd get the result above.
