On the chart we commence by drawing a line from 0.sixty five pa/m the many way up and then attract a line throughout from our needed volume stream rate, In cases like this for part C we'd like 0.21m3/s. At this intersection we draw a line to discover the velocity and we could see that it falls within the strains of 3 and 4m/s so we have to estimate the worth, in this case it is apparently about 3.
