Hi, Nindi and mas Raihan. The simulation i carried out also displayed the same results (-1.1561628e-13 [kg/s]). I agree with Mr. Raihan that the results of the simulation I carried out were essentially zero. Because in theory mass balance means mass_in = mass_out, but in practice there is something called the amount of mass accumulated in the system so it is possible that there is a small difference in mass in the pipe.
