The diameter of the water column does not affect the pressure.It is the height of the column that determines the pressure at the base.(and also the barometric pressure and temperature).

10 inches of water column equals to how much gas pressure?
.4 psi
500 mm water column is equivalent to approximately 0.05 bar pressure.
The diameter of the water column does not affect the pressure.It is the height of the column that determines the pressure at the base.(and also the barometric pressure and temperature).
35 inches of water is equivalent to approximately 1.27 psi. This can be calculated by dividing the height of the water column (35 inches) by the conversion factor (27.71 inches of water column per psi).
since mercury (Hg) is much more dense than water, x mm of Hg is a higher pressure than x inches of water column (in wc) or x mm of water column.Inches of water and millimeters of mercury are both the measure of pressure by equating the pressure to a height of a column of fluid (pressure-fluid height relationship) and thus, the density of the fluid greatly affects the pressure measurement.
12psi
Low pressure - 6 to 7 inches water column, equivalent to 4 ounces or 1/4 PSI, is the standard pressure supplied by natural gas utilities in the USA and Canada. Check with your local utility if you need to increase the pressure for your use. Most natural gas appliances manufactured for use in the US are designed to operate up to a maximum of 14 inches water column.
12.01 psi

30ft rise = 13 psi (pressure is 13 psi higher at bottom of a 30ft column that at the top). Water Pressure = .433 psi per ft for a column of water at 62 degrees F.
Water pressure increases by 9.81 kilopascals (kPa) for every meter of depth due to the weight of the water column above. This principle is known as hydrostatic pressure.
