CONTINUITY EQUATION Fluid FlowSo by using the continuity equation, we find that the increase in pipe diameter from 6 to 8 inchesm1m2r1 A1 v1r2 A2 v2v2v1r1r2A1A2v1p r21p r2222.4ftsec(3 in)2(4 in)2v212.6ftseccaused a decrease in flow velocity from 22.4 to 12.6 ft/sec.The continuity equation can also be used to show that a decrease in pipe diameter will cause anincrease in flow velocity.Figure 3 Continuity EquationHT-03 Page 12 Rev. 0
