WebThe Venturi measures a fluid's flowrate by reducing the cross sectional flow area in the flow path and generating a pressure difference. After the pressure difference is generated, the fluid is passed through a pressure recovery exit section where up to 80% of the differential pressure generated at the throat is recovered. Daniel Bernoulli. WebThis is expressed in the Continuity Equation: Where: Q = the volumetric flow rate. A = the cross sectional area of flow. V = the mean velocity.
