### mass flow rate

The mass flow rate () is defined as the amount of mass flowing through a cross-section per unit timeThe mass flow rate of a fluid flowing in or out of a pipe or duct is proportional to the cross-sectional area (A) of the pipe or duct, the density of the fluid (ρ), and the velocity of the flow (V)The flow rate through a differential area dA is:
Jun 12, 2014· If we have a tube with changing area, like the nozzle shown on the slide, the maximum mass flow rate through the system occurs when the flow is choked at the smallest area This location is called the throat of the nozzle The conservation of mass specifies that the mass flow rate through a nozzle is a constant
Sometimes, mass flow rate is termed mass flux or mass current, see for example Fluid Mechanics, Schaum's et al In this article, the (more intuitive) definition is used Mass flow rate is defined by the limit:
Volumetric flow rate In fluid dynamics, the volumetric flow rate, also volume flow rate and rate of fluid flow, is the volume of fluid which passes through a given volume per unit time (for example cubic meters per second [m 3 /s] in basic SI units or ft 3 /s)

Share Mass flow rate Mass flow rate is the mass of substance which passes through a given surface per unit time Its unit is mass divided by time, so kilogram per second in SI units, and slug per second or pound per second in US customary units
Flow rate and velocity are related, but quite different, physical quantiti To make the distinction clear, think about the flow rate of a river The greater the velocity of the water, the greater the flow rate of the river But flow rate also depends on the size of the river
The mass flow rate is the mass of the fluid traveling past a fixed point per unit time The mass flow meter does not measure the volume per unit time (eg, cubic meters per second) passing through the device; it measures the mass per unit time (eg, kilograms per second) flowing through the device
