WebApr 17, 2024 · External Static pressure is measured using a manometer and is expressed in inches of water column (i.e., #” WC). The air flow rate or CFM of a motor is directly related to the external static pressure. The higher the ESP, the lower the CFM. The lower the ESP, the higher the CFM. WebInch of water (inH2O - Water), pressure. Because pressure is commonly measured by its ability to displace a column of liquid in a manometer, pressures are often expressed as a depth of a particular fluid (e.g. inches of water). The most common choices are mercury (Hg) and water; water is nontoxic and readily available, while mercury's density ...
