On the chart we commence by drawing a line from 0.sixty five pa/m many of the way up after which you can attract a line across from our demanded volume move rate, In cases like this for area C we need 0.21m3/s. At this intersection we attract a line to locate the velocity and we could see that it falls inside the traces of 3 and 4m/s so we have to estimate the worth, In this instance it is apparently about 3.
