Over the chart we get started by drawing a line from 0.65 pa/m every one of the way up and then draw a line throughout from our required volume stream rate, In cases like this for portion C we need 0.21m3/s. At this intersection we draw a line to discover the velocity and we could see that it falls throughout the lines of 3 and 4m/s so we need to estimate the value, In such cases it is apparently about three.
