Because the total flow at any location in the valve is the same, the liquid velocity in the reduced area (vena contracta) must be much higher to pass the same flow. Figure 2. This graph shows a ...

Open the surge tank valve. Open both the head and the tail ... Using your depth measurements upstream and at the vena contracta, along with the continuity and energy equations, compute the flow rates ...

NEW research has revealed that residual mitral regurgitation (MR) assessed by 3D -Vena Contracta Area (VCA) during ...
