Within the chart we begin by drawing a line from 0.65 pa/m many of the way up then draw a line across from our expected volume circulation rate, in this case for area C we'd like 0.21m3/s. At this intersection we attract a line to find the velocity and we will see that it falls inside the traces of 3 and 4m/s so we must estimate the worth, in this case it is apparently about three.
