Conteúdo: | A computer model was developed to combine pump curves in series and / or in parallel and to determine the performance of the pump station and of individual pumps within the station. Polynomial equations are fit to the individual pump curves and to the combined pump station curve. Cubic spline interpolation is employed to combine curves of pumps with different sizes. Performance indicators of the station and of each pump within the station are calculated for the entire station flow rate range. This way the performance of individual pumps or of the pump station can be analysed for different situations of an existing or desirable water distribution system or irrigation system. A graphycal interface designed for windows 95 and 3 xx allows the user to draw the pump station layout and to view the discrete data entered along with the equations fit. Data entered, plots of the curves and equation coeficients can be printed out.
