We go ahead and take chart and scroll up from The underside left right until we strike the volume flow rate of 0.79m3/s. Then we locate where by the velocity line is of 5m/s and we draw a line throughout until eventually we strike that. Then to discover the stress fall we draw a vertical line down from this intersection. Within this occasion we see it arrives out at 0.
