Meteorological data includes windspeeds which may be expressed as statute miles per hour, knots, or meters per second. Here are the conversion factors for those various expressions of windspeed: 1 m/s = 2.237 statute mile/h = 1.944 knots 1 knot = 1.151 statute mile/h = 0.514 m/s 1 statute mile/h = 0.869 knots … See more Various governmental agencies involved with environmental protection and with occupational safety and health have promulgated regulations limiting the allowable concentrations of gaseous pollutants in … See more Atmospheric pollutant concentrations expressed as mass per unit volume of atmospheric air (e.g., mg/m , µg/m , etc.) at sea level will decrease with increasing altitude because the atmospheric pressure decreases with increasing altitude. The change of See more • Standard conditions of temperature and pressure • Units conversion by factor-label • Atmospheric dispersion modeling See more The conversion equations depend on the temperature at which the conversion is wanted (usually about 20 to 25 degrees Celsius). At an ambient air pressure of 1 atmosphere (101.325 kPa), the general equation is: See more A normal cubic meter (Nm ) is the metric expression of gas volume at standard conditions and it is usually (but not always) defined as being … See more Many environmental protection agencies have issued regulations that limit the concentration of pollutants in gaseous emissions and define the reference conditions applicable to those concentration limits. For example, such a regulation might … See more • More conversions and formulas useful in air dispersion modeling are available in the feature articles at www.air-dispersion.com . • U.S. EPA tutorial course See more WebQ = Volumetric flow rate of exhaust gases, dscm/hr (dscf/hr); K 1 = Conversion factor, 1 kg/1,000 g (1 lb/lb); K 2 = Conversion factor, 1,000 L/m 3 (1 ft 3 /ft 3 ); M v = Molar volume, 24.45 L/g-mole (385.3 ft 3 /lb-mole); and P = Production rate, Mg/hr (ton/hr).

C s = concentration of SO 2, kg/dscm (lb/dscf). S = acid production rate factor, 368 dscm/metric ton (11,800 dscf/ton) of 100 percent H 2 SO 4 produced. cody lee 李
