The functions provided by this application are as follows.
1) Obtaining the air volume from the nozzle differential pressure and nozzle information measured at the test facility
2) Selecting a suitable fan type using the fan operating conditions (rotational speed, pressure, air volume)
3) Estimating efficiency with information on flow rate, pressure, torque, and rotation speed of a rotating body such as a fan or pump
4) Estimating the amount of change in air volume, pressure, and noise according to the change in fan condition (number of rotations, diameter)
