# one cubic meter tank contains of 1000 liter water. how to calculate the pressure?

If the one cubic meter squre tank contains of 1000 liter water, if we fit one pressure guage on the bottom of the tank how much pressure will be there in the guage? how many psi/bar.

if it is a round tank then what about the calculation?

Relevance

1 METER = 39.37 INCHES

1 POUND H2O = 27.7 INCHES (HARD WATER)

SO......39.37 INCHES H2O/ 27.7 INCHES = 1.42 POUNDS

THUS IF YOUR GAGE MEASURES IN 1/10 PSI INCREMENTS YOU WILL VISUALLY SEE 1.4 PSI READING ON YOUR GAGE AT THE BOTTOM OF A CUBIC METER TANK..

FOR A ROUND TANK (HORTEN SPHERE) YOU DO THE MATH AND USE THE HIGHTH OF THE TANK AND THE FORMULA ABOVE TO CALCULATE THE PSI

• Neither Dr or Jeff above is right. Pressure is force divided by area. Weight is a force equal to m*g, so a cubic meter of water weighs 1000*9.81 = 9810 N. If the bottom of the tank is 1m², the pressure will be 9810 N/m² = .0981 bar = 1.422 psi

• One cubic meter weights 1000 Kg. Divide this by the bottom surface of the tank and you will get the pressure.
