Tiny Cooling Fan performance curve test mode

Test "Tiny Cooling Fan" performance curve instrument used for wind tunnel, wind tunnel is the use of the law of conservation of energy, the kinetic energy is converted into wind tunnel air flow inside the nozzle evenly on both sides of the pressure difference, the use of compensation "Tiny Cooling Fan" to adjust the hydrostatic test For the value of the static pressure to the tank test, and can utilize both sides of the nozzle pressure differential calculated air flow rate flowing through the nozzle, and then multiplied by the known area of the nozzle can be obtained under a static pressure of the air flow, after testing multi-point (including the point of maximum static pressure and the maximum flow rate), will be able to draw "Tiny Cooling Fan" performance curve.
