what is mass flow rate
Mass Flow Rate Fluids Floww Equation. The mass flow rate of a system is a measure of the mass of fluid passing a point in the ( Ë m) system per unit time. The mass flow rate is related to the volumetric flow rate as shown in Equation 3-2 where r is the density of the fluid. If the volumetric flow rate is in cubic feet per second and the density is in pounds-mass per cubic foot, Equation 3-2 results in mass flow rate measured in pounds-mass per second. Other common units for measurement of mass flow rate include kilograms per second and pounds-mass per hour.
