To determine the pressure generated by a 40 feet of Diesel, you will need to know the specific gravity (S.G.). How would I determine the pressure range required to measure a 40′ deep diesel storage tank? Help Pressure generated by 40 foot high tank of Diesel The calculation determines the difference in pressure between the bottom of the liquid column and the surface of the liquid, therefore it excludes any pressure contribution from air or a gas on the surface. This is the calculated head pressure expected from the entered values for liquid level, specific gravity and local gravity. The default value is set to 9.80665 ms -2 which is standard gravity. The local gravity is dependent on several factors such as latitude, height above sea-level, local geological density, etc… Refer to your national geological survey data for your location or use this local gravity calculator to determine a close approximation. Local Gravity (g)Įnter the acceleration due to gravity for your geographical location in metres per second per second (ms -2).
The default value is set to an SG of 1.00, which corresponds to fresh water at 4 degrees Celsius. Specific Gravity (SG)Įnter here the ratio of liquid density compared to the density of fresh water (1000 kg/m 3). fresh water = 1)Įnter the measured liquid depth to, or the height of fluid from a point at which the hydrostatic pressure is to be calculated.
ρ 0 = Density of fresh water (1000 kgm SG = Specific gravity of liquid (e.g.The calculation formulas used for this tool are: P = L x ρ x g ρ = ρ 0 x SG Symbols This calculator and conversion scale will convert the height or depth of a fluid in any units to a measurement of hydrostatic head pressure, and display a list of conversion values above and below the entered liquid level.
