WebThe volumetric flow rate formula used by this calculator is: Q = v · A. Symbols. Q = Volume flow rate; v = Flow velocity; A = Cross-sectional area; n.b. This formula assumes uniform flow conditions within the entire cross-sectional area, without any friction losses near to surfaces. Flow Velocity Measured. Enter the speed at which the ... WebFlowmeters are devices that measure the amount of liquid, gas or vapor that passes through them. Some flowmeters measure flow as the amount of fluid passing through the flowmeter during a time period (such as 100 liters per minute). Other flowmeters measure the totalized amount of fluid that has passed through the flowmeter (such as 100 liters).
