One inch of water column is equal to a pressure of approximately 1/28 pound per square inch (psi). Stating this another way, a column water 28-inches high produces pressure that is equal to 1 psi.
What is 5 PSI in inches of water column?
To convert PSI to WC, just multiply the PSI measurement by 27.708 to get the measurement in WC. For example, if you divide 5 PSI by 27.708, it converts to about 138.54 inches WC .
What is 10 PSI in inches of water column?
| Inches of Water Pound force per square inch | 8 in H20 0.29 psi | 9 in H20 0.33 psi | 10 in H20 0.36 psi | 11 in H20 0.40 psi |

How many inches of water column are in 2 PSI?
A pressure of 1/28 pound per square inch is equal to one inch of water column. The column water is 28 inches high and has the same pressure as 1 psi.
How much pressure is in a column of water?
The density (or unit weight) of water is 0.036 pounds per cubic inch. Therefore, the pressure of 1 inch of water in a water column is 0.036 psi or 1/28 psi . In other words, a column of water 28-inches high will produce a pressure equivalent to 1 psi.
What does 11 inches of water column mean?
This total measurement represents the inches of water column pressure. For RV appliances to operate properly, and safely the operating pressure should be 10 1⁄2 to 11 inches of water column. ... If the LP gas operating pressure is too high or too low you can adjust it at the RV regulator.
What is the pressure in psi of a column of water 8 inches in height?
| Height of Water Column Pressure | (m) (ft) (psi) | 7 23.0 10.0 | 8 26.2 11.4 | 9 29.5 12.8 |

How do you measure inches of water column?
To calculate the hydrostatic pressure at the bottom of the container consider: H = 8 inches of water SG = 1 P = x PSI P=1 • 8 inches = 8 inches W.C. So the hydrostatic pressure (P) at the base is equivalent to 8 inches of water column. 1 inch of water column = 0.03613 PSI (27.678 inches of water column = 1 PSI).
How many inches of water column is 1lb?
Use the fact that 1 pound per square inch
Why is inches of water column used?
It is also given as inches of water gauge (iwg or in. w.g.), inches water column (inch wc or just wc), inAq, Aq, or inH 2 O. The units are conventionally used for measurement of certain pressure differentials such as small pressure differences across an orifice, or in a pipeline or shaft .
How high can a column of water reach atmospheric pressure?
Since normal atmospheric pressure is about 10 5 N/m 2 (or 10 5 Pascals), you would need a mercury column of 0.76 meters (or 760 mm—a common unit for pressure). Using water would require a column 10 meters tall . That’s just too tall to be practical.
How high does my water tank need to be for good pressure?
If your tank is positioned high enough, then you can “gravity feed” water to your taps without the use of a pump. Understand however, for decent water pressure your tank has to be about 10 metres higher .
What pressure is 11 WC?
WC stands for Water Column and is measured in inches. It is a measurement of pressure under 1 PSI . Most gas companies deliver gas to your home at 11′′ WC. 27.7′′ WC is equal to 1 PSI.
Is water gauge the same as water column?
W.G. — Water Gauge (plus a height dimension). ... — Water Column or Column of Water. Inches H20 — Inches of Water (Column). S.P. — Static Pressure (usually in inches).
