The density of mercury is 13.534, compared to '1' for water. So the water columnis 13.534 times as high as the mercury column at the same pressure.(30 inches of water) x (25.4 millimeters/inch) / 13.534 = 56.3 millimeters of mercury
0.5 psig = 420.62 inches of 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 column with the smallest diameter has greater pressure and the column with a larger diameter has less pressure.
Head pressure is created by a column (depth) of water in a container. Pipe is considered a container. Diameter is not a factor. The higher the column of water, the more psi it creates. Multiply column height of water by .434 to get psi of water.
0.25 psig = 413.7 inches of water column
10 inches of water column equals to how much gas pressure?
27.71 inches of water column equals 1 psi
Water column head is expressed either as the height of the column ... 6 meters here ... or else as the pressure at the bottom ... 58.842 kPa here. 'Kg' can't be a unit of water column head, and the diameter of the column is irrelevant.
Absolutely.
That depends on how wide the column is.
This section of the ocean from floor to surface is called the water column.
