This method is most suitable to analyse the gas and gas network. To perform this calculation, you need to press the “Calculate“ button in the working field and select the “Gas flow method“ option. Currently, this algorithm does not support the following items:
Pump;
In the main window of settings the user can choose the loss estimation equation which will be used by algorithm during the flow calculations.
The "General flow equation" (1), also known as "Fundamental flow equation", is one of the basic equations used for isothermal analysis of stable gas networks. From this equation, the following equations are derived:
(1)
The Panhandle A equation (2) was derived for the analysis of natural gas networks. This equation uses the pipe efficiency variable but does not use surface roughness. Applicable when the number of Reinalds is between 5 and 11 million:
(2)
The Weymouth equation (3) is used for the analysis of high pressure, high flow and wide-diameter pipe gas systems. This equation evaluates the losses using variables of gas compression, specific weight, pipe length, diameter and efficiency.
