This mass flow rate calculator helps you determine the mass flow rate of a material or the other three components of the equation, density velocity or flow area.

Flow meters are devices that are used to measure the flow rate of a certain liquid or gas. They can measure these substances in terms of the volumetric flow rate or the mass flow rate. The volumetric flow rate is generally given in

Computer drawing of an afterburning turbojet engine with the equation for thrust. Thrust equals the exit mass flow rate times exit velocity minus free stream mass flow rate times velocity.

Computer drawing of a liquid rocket engine with the equation for thrust. Thrust equals the exit mass flow rate times exit velocity plus exit pressure minus free stream pressure times nozzle area.

Computer drawing of a rocket nozzle with the equation for thrust. Thrust equals the exit mass flow rate times exit velocity plus exit pressure minus free stream pressure times nozzle area.

Computer drawing of a turbofan engine with the equation for thrust. Thrust equals the sum of the exit mass flow rate times exit velocity minus free stream mass flow rate times velocity for both streams.
