We go ahead and take chart and scroll read more up from the bottom left until we hit the volume move level of 0.79m3/s. Then we locate the place the velocity line is of 5m/s and we draw a line throughout right up until we strike that. Then to find the strain drop we attract a vertical line down from this intersection. Within this instance we see it comes out at 0.
