Within the chart we start off by drawing a line from 0.sixty five pa/m many of the way up and then draw a line across from our needed volume here movement charge, In cases like this for area C we'd like 0.21m3/s. At this intersection we attract a line to locate the velocity and we could see that it falls throughout the strains of three and 4m/s so we have to estimate the value, In cases like this it appears to be about 3.
