10" Water Column equals about .4 Pounds per Square Inch
or
0.36127291827412783psi exactly.
About 2 1 pound per square inch = 2.0362... inches of mercury
Inches of mercury x 0.4912 = psi
You need to know how high the water column is to calculate the pressure it exerts at its base! For example, a column of water 1 metre deep would exert a pressure of 9.81 kPa at its base (density x gravity x depth - 1000 * 9.81 * 1). This would be equal to approx 1.42 PSI.
Inches of water x 0.03613 equals pounds per square inch (psi).
27.7 "h2o
You need to multiply by 0.036. So 5 x 0.036=.18 psi
27.71 inches of water column equals 1 psi
Multiply inches of WC by 0.0361 to obtain PSI.
0.25 psig = 413.7 inches of water column
1 psig is equivalent to 51.71 mm (2 in) of mercury or to approx 700 mm (27.5 in) of water. Technically one cannot have apsig. Psig represents a pressure reading of the pressure above normal atmospheric pressure of 14.7 psi. You mean a psi.
Multiply by 0.036 http://www.enercongroup.com/conversion_factors.htm One PSI is equal to 27.7 inches of water column
.4 psi
One psi (pounds per square inch) is 27.7 inches of water. An inch of water is a unit of pressure which will raise water one inch. A cubic inch of water weighs 0.0361 pounds, so one psi is one over 0.0361 or 27.7 inches of water.
Inches of water x 0.03613 = psi
35 inches of water = 1.26 psi
10 psi.
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.
