A popular popular pump proxy model is given by the quadratic equation:
...
| LaTeX Math Inline |
|---|
| body | --uriencoded--\delta p_%7B\rm max%7D |
|---|
|
| maximum pressure gain that pump can exert over the input pressure |
|---|
| maximum flowrate that pump can produce |
|---|
| total hydraulic pump friction (dimensionless) |
|---|
| pump efficiency efficiency |
|---|
| maximum pump efficiency |
|---|
The plunger pump and centrifugal Many pumps can be normally adjusted by the variation of the working frequency frequency which affects the maximum the maximum pump flowrate as:
| LaTeX Math Block |

q_{\rm max} = q^*_{\rm max} \cdot \frac{f}{f^*} |
where
