Torricelli's law, also known as Torricelli's theorem, is a theorem in fluid dynamics relating the speed of fluid flowing from an orifice to the height of fluid above the opening. The law states that the speed v of efflux of a fluid through a sharp-edged hole at the bottom of the tank filled to a depth h is the same as the speed that a body (in this case a drop of water) would acquire in falling freely from a … Webwhere: A = orifice area, B = orifice diameter or width and height, C c = contraction coefficient, C v = velocity coefficient, C o = orifice coefficient = C c C v, g = acceleration due to gravity = 32.174 ft/s 2 or 9.8066 m/s 2, … showcase auto and sons
