Modeling and approximation of performance characteristics of pumping and power units of a pumping station of a main pipeline in a city water supply network

In the presented article, the problem of qualitative modeling and polynomial approximation of the operating characteristics of pumps of a pumping station (PS) of extended pipelines of a city water supply network is solved. The solution of this problem is a necessary and important element of the urgent problem of the optimal choice of the type and number of pumping and power units, which ensures a decrease in the cost of the pumping unit and energy consumption when the amount of water is supplied to the pipeline in a set range.
