To the chart we get started by drawing a line from 0.sixty five pa/m all the way up after which get more info draw a line across from our necessary volume circulation fee, In such cases for portion C we want 0.21m3/s. At this intersection we attract a line to locate the velocity and we can easily see that it falls throughout the strains of three and 4m/s so we must estimate the worth, In such cases it appears to be about three.
