I could also explain the difference between the two methods, based on an example found in the forum.I also applied the numerical integration to found the flow rate of a pump during the start up and shut down processes, which is useful to some degree for many engineers.Hope it help, Kind regards, romberg_integration_exmple.sm (38kb) downloaded 23 time(s). romberg_integration.sm (31kb) downloaded 22 time(s).
