Flow energy units
In physics and engineering, mass flow rate is the mass of a substance which passes per unit of time. Its unit is kilogram per second in SI units, and slug per second or pound per second in US customary units. The common symbol is $${\displaystyle {\dot {m}}}$$ (ṁ, pronounced "m-dot"), although … See more Mass flow rate can also be calculated by: $${\displaystyle {\dot {m}}=\rho \cdot {\dot {V}}=\rho \cdot \mathbf {v} \cdot \mathbf {A} =\mathbf {j} _{\rm {m}}\cdot \mathbf {A} }$$ where: See more In hydrodynamics, mass flow rate is the rate of flow of mass. In electricity, the rate of flow of charge is electric current. See more In the elementary form of the continuity equation for mass, in hydrodynamics: $${\displaystyle \rho _{1}\mathbf {v} _{1}\cdot \mathbf {A} _{1}=\rho _{2}\mathbf {v} _{2}\cdot \mathbf {A} _{2}}$$ In elementary classical mechanics, mass flow rate is … See more • Continuity equation • Fluid dynamics • Mass flow controller See more Both gas and liquid flow can be measured in physical quantities of kind volumetric or mass flow rates, with units such as liters per second or kilograms per second, respectively. These measurements are related by the material's density. The density of a liquid is almost independent of conditions. This is not the case for gases, the densities of which depend greatly upon pressure, temperature and to a lesser extent, composition.
