| Abstract: | In order to realize the automatic conversion and drawing of the performance curves for a pump or a fan, the experiment data are fitted by the method of least square and programmed by the Visual Basic. When the experimental data of a pump or a fan are available under a given rotation speed, its performance curves can be drawn quickly. The performance curves can be converted and drawn for other rotation speed. |
