We go ahead and take chart and scroll up from the bottom still left right until we strike the amount circulation fee of 0.79m3/s. Then we locate in which the velocity line is of 5m/s and we attract a line across until finally we hit that. Then to find the strain drop we attract a vertical line down from this intersection. In this instance we see it will come out at 0.
In addition they supply free webinars, courses and tutorials to help you put in place and operate your own personal simulations.
