Obtain the proper information to make the calculation. Since you are using an equation, you need to know the values and units of all the parameters required to use the equation. You therefore need to know specific gravity of liquid and the value and unit of pressure on the surface of liquid in the pressurized tank. If the tank is open, the pressure on the surface of the liquid is atmospheric pressure. At sea level, the standard value for atmospheric pressure is 29.92 inches or 760 millimeters of mercury.
Convert pressure in inches of mercury to head feet. Calculate height in inches of mercury times 1.133 divided by specific gravity with the aid of a calculator to obtain head in feet.
Convert pressure in millimeters of mercury to head in feet. Calculate height in millimeters of mercury divided by 22.4 divided by specific gravity with the aid of a calculator to obtain head in feet.
Convert pressure in pound per square inch to head in feet. Calculate pound per square inch times 2.31 divided by specific gravity with the aid of a calculator to obtain head in feet.
Convert pressure in bar to head in meter. Calculate pressure in bar times 10.197 divided by specific gravity with the aid of a calculator to obtain head in meter.
Convert pressure in kilogram per square centimeter to head in meter. Calculate pressure in kilogram per square centimeter times 10 divided by specific gravity with the aid of a calculator to obtain head in meter.
