One would assume that when the area of an orifice is doubled then twice as much water will flow through this orifice. Hence we assume a proportional relationship between the two. However use of a garden hose leads us to believe that increasing the area of the orifice decreases the velocity of the water hence implying an inverse relationship.(adsbygoogle = window.adsbygoogle || []).push({});

I need a theoretical relationship between the diameter of a circular orifice and the flow rate of water discharged from this orifice.

Your help would be greatly appreciated
