Free Surge Analysis Software – Download – PASSWORD: SPARTA

This program calculates surge along a  pipeline  transferring water by gravity from a fixed head reservoir due to  rapid or slow closure of a valve at the discharge point.

The first step is to fill all the parameters in window 1 as shown in the image below:

surge Analysis

The main (pipe) is divided into 9 nodes, the height of the reservoir  remains unchanged during the whole simulation and the head at valve at time = 0  is specified by the user (Head= Pressure +Height, Datum is the height of the reservoir).

The second step is choosing which node to analyse, the selection is made in window 2 as shown in the image below:

The last step before calculating and saving is to specify the directory in which the excel file will be generated and saved, Remember, do not use the same file name for 2 different scenarios, that will throw an error.
