This method is given in two forms: original Hardy Cross method-successive substitution methods and improved-simultaneous solution method (Newton-Raphson group of methods). Problem of gas flow in looped network is nonlinear problem; i.e. relation between flow and pressure drop is not linear while relation between electric current and voltage is. Improvement of original method is done by introduction of influence of adjacent contours in Yacobian matrix which is used in calculation and which is in original method strictly diagonal with all zeros in non-diagonal terms. In that way necessary number of iteration in calculations is decreased. If during the design of gas network with loops is anticipated that some of conduits are crossing each other without connection, this sort of network became, so there has to be introduced corrections of third or higher order.}, author = {Brkic, Dejan}, doi = {10.1016/j.apenergy.2008.10.005}, journal = {Applied Energy}, month = {jul}, pages = {1290-1300}, title = {An improvement of Hardy Cross method applied on looped spatial natural gas distribution networks}, url = {https://zenodo.org/record/890132/files/article.pdf}, volume = {86}, year = {2009} } @article{Brkić1970, abstract = {This review paper gives Excel functions for highly precise Colebrook’s pipe flow friction approximations developed by users.

Accuracy of the friction factor computed using nine to date the most accurate explicit approximations is compared with the sufficiently accurate solution obtained through an iterative scheme which gives satisfying results after sufficient number of iterations. The codes are given for the presented approximations, for the used iterative scheme and for the Colebrook equation expressed through the Lambert W-function (including its cognate Wright ω-function). The developed code for the principal branch of the Lambert W-function has additional and more general application for solving different problems from variety branches of engineering and physics.
