Least square method of polynomial or the method based on the given function are used to fit pumpcharacteristic curve in pump selection or operation.
在水泵的选型或运行中，通常采用多项式的最小二乘法或根据假设的函数关系来拟合水泵性能曲线。
2
Determined that it is very important by comparing the total more accurate pumpcharacteristic curve in the calculation of water hammer protection position.
通过比较确定较准确的水泵全特性曲线在水锤防护计算中有十分重要的地位。
3
Centrifugal pumpcharacteristic curve on the efficiency of the highest point known as the design point, a pump at the point corresponding to pressure head and flow of work under the most economic.
