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

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.

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.
The steam pressure (assuming this is a closed container) will be entirely dependent on the temperature. Look up steam tables to get the pressure of saturated steam at various temperatures.
Purely a matter of convenience. A water barometer is entirely feasible, but the column height at normal atmospheric pressure is over 32 feet tall. In order to make the barometer more compact, it's convenient to use the heaviest available liquid. Mercury has a little more than 13 times the density of water, so the column height in a mercury barometer is only about 30 inches tall, making for a much more manageable instrument.
10 feet x 0.433 psi/ft = 4.33 psi at the base of the cylinder.
