  My code is wrong in the driver for wind speed or the sensor is not good enough at such low speeds.   Measured with an anemometer Exhaust velocity  6.864  m/Sec mean  Mass Flow  0.121296892 m/Sec3  That's  7.2778  m/Min3  Therefore it is extracting 165m3 in 23 minutes That what I originally wanted 8 m/Min3 woo hoo
