The air-to-cloth ratio is the volumetric flow rate of air (m 3 /minute; SI m 3 /second) flowing through a dust collector's inlet duct divided by the total cloth area (m 2) in the filters. The result is expressed in units of velocity .
In most other nations, the reference ambient temperature for pollutant limits may be 0 °C or other values. 1 percent by volume = 10,000 ppmv (i.e., parts per million by volume). atm = absolute atmospheric pressure in atmospheres; mol = gram mole
