We take the chart and scroll up from The underside still left 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 finally we strike that. Then to find the force drop we attract a vertical line down from this intersection. In this instance we see it arrives out at 0.
