Asked by Tom
The velocity v of a fluid flowing in a conduit is inversely proportional to the cross- sectional area of the conduit.( Assume that the volume of the flow per unit of time is held constant .) Determine the change in the velocity of water flowing from a hose when a person places a finger over the end of the hose to decrease its cross-sectional area by 25%

%CV = 1.25Vo. Where Vo is initial velocity
Change = 1.25Vo-Vo = 0.25Vo.
%Change = (0.25Vo/Vo)*100% = 25%.
