Over the chart we start by drawing a line from 0.65 pa/m many of the way up then attract a line throughout from our required volume flow amount, In this instance for portion C we'd like 0.21m3/s. At this intersection we attract a line to find the velocity and we are able to see that it falls in the traces of three and 4m/s so we have to estimate the worth, In such cases it appears to be about 3.
