Flow rate vs volumetric flow rate

WebDischarge or Flow Rate. Discharge (also called flow rate) The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate. WebVolumetric flow meters are types of flow meters that operate linearly with respect to the volume flow rate – they make a flow measurement of the amount of either a liquid or a gas flowing through a pipe by measuring the velocity at which it is flowing. Volumetric flow meters measure volumetric flow rate, differing from mass flow meters, like Coriolis …
