Mass flow through the rocket engine Calculator

Mass flow through a rocket engine refers to the rate at which propellant material (usually a combination of fuel and oxidizer) is being consumed and expelled from the engine to produce thrust. In a rocket engine, propellant is burned in a combustion chamber to generate high-speed exhaust gases. These gases are expelled through a nozzle at the rear of the engine, creating a reactive force known as thrust that propels the rocket forward.
