Flow measurement Using Bernoulli’s equation it may be shown that the velocity of water passing through an orifice in the base of a tank is given by the relationship . If we multiply both sides of the equation by A, the area of the hole, we have . Since v.A = Q we get , in theory. In practice there is a significant loss of energy for the fluid passing through the orifice and the actual flow is given by , where Q is the rate of flow in A is the area of the hole in . H is the Head of water above the orifice, in meters. is a factor determined by the shape of the hole. Using Bernoulli’s equation it may be shown that the velocity of water passing through an orifice in the base of a tank is given by the relationsh...
