    It has the least diameter along the length of the venturi pipe. The reading is converted into a volumetric flow rate that is calculated by multiplying the cross-sectional area. A venturi meter was fitted in a pipe of 0. The reason for this phenomenon is that fluid streamlines cannot abruptly change direction. Mathematics Stack Exchange works best with JavaScript enabled. For example, an unrestricted jet that has an abrupt diameter difference along its length can lead to the interruption of the streamlines due to the immediate angular change Baum, Equation 4 can be modified to mass flow for fluids by simply multiplying with the density:.

    It is the section in fluid stream were cross-section of stream became minimum. At vena contracta.Could you reformulate your answer in terms of that to relate the streamlines to the pressure?

    Vena contracta is the point in a fluid stream where the diameter of the stream is the least, and fluid velocity is at its maximum, such as in the case of a.The effect is also observed in flow from a tank into a pipe, or a sudden contraction in pipe diameter.

    the jet falls and picks up speed v, its cross-sectional area A must decrease according to the vA = constant. 1. Page 2. where P is pressure and.In addition, the speed before the contraction is different to the velocity after contraction; hence, the force in the vena contracta zone increases significantly.

    Only in the vena contracta does the flow velocity becomes uniform, and the pressure atmospheric, all the way across the jet.I am curious about the common explanation for the vena contracta effect that occurs as a flow moves around a sharp corneror within a free jet of liquid issuing from a nozzle.

    Since the amount of energy in the flowing fluid should be conserved, the drop in pressure is realized; hence, it helps in measuring the velocity.Click here to contribute.

    When the fluid passes through the orifice, a jet is formed. The point of jet where area is minimum, pressure energy is minimum and velocity is maximum is called.Coefficient of contraction C c is defined as the ratio of the area of cross-section of vena contracta to the area of cross-section of the orifice.

    The definition of the streamline is that at every point within a flow, the streamline is a path that is always tangent to the local velocity vector.
