Problems involving fluid flow in pipeline usually require outflow, pressure drop, temperature and diameter calculation. To solve these problems, conservation laws related to mass conservation, momentum and energy are applied to one-dimensional flows. Due to problem complexity, the solution is, in general, only achieved through computational programs.
Well known international software is employed to carry out simulations, for example:
