masseflow
Masseflow is a term used to describe the rate at which mass passes through a cross-section of a flowing substance per unit time. In English, the standard term is mass flow (or mass flow rate), commonly denoted by ṁ and measured in kilograms per second (kg/s). For a liquid or gas with density ρ, the mass flow rate is related to the volumetric flow rate Q by the equation ṁ = ρQ. In compressible flows, such as those involving gases, density can vary with pressure and temperature, so ṁ may remain constant even as Q changes.
Measuring masseflow can be done directly or indirectly. Direct methods use mass flow meters, with Coriolis
Applications of masseflow measurements span many industries. In engines and fuel systems, precise mass flow control
Note: masseflow is often used as a variant spelling or translation of mass flow in non-English sources
