Mass Flow Rate Equation - Density of the flowing liquid or gas, in kg/m^3 v:. The flux out of the cstr is similarly equal to the product of volumetric flow rate in the exit pipe times the concentration in the exit pipe. The mass flow's equation is: The equations m& = ρav = ρq assume that density is constant across a section. If the fluid is incompressible, like liquid water in both of these flow rates are used in many different kinds of calculations so i will focus on one of them: Measurements of mass flow are preferred over measurements of volumetric flow in process applications where mass balance (monitoring the rates of mass entry and exit for a process) is important.
Volumetric water flow rate in imperial units. The conservation of mass is telling us that the mass flow rate through a tube must be constant. Considering the mass flow rate equation, it appears that for a given area and a fixed density, we could increase the mass flow rate indefinitely by simply increasing the velocity. In the same way, velocity from mass flow rate can be calculated using the above equation of mass flow rate. M = ρ * v * a where:
