Volume Flow Measurement Correction Factors (where L = const.) The volume flow can be determined by measuring the airvelocity with zero blade divergence using either a pitot tube or a rotating vane anemometer.Pitot tube (Figure 1):Measurements of air velocity should be made between the blades at a number of positions to determine an arithmetic mean value v > Figure1Figure2 109 eff.mean .The volume flow is then calculated as follows:V. > t [l/s]= v > eff.mean [m/s] x A > eff [m > 2 ] x 1000V. > t [m > 3 /h]= v > eff.mean [m/s] x A > eff [m > 2 ] x 3600Rotating Vane Anemometer (Figure 2):The...
