Fuel mass flow rate equation
WebApr 5, 2024 · The mass flow rate formula is the volume of mass that passes through a plane. The principle of mass conservation (continuity) states that the mass flow rate equation into a conduit is constant. The mass flow rate can be calculated using the flow conditions. The mass flow rate equation formula is given by, \[\dot{m}\] = \[\frac{dm}{dt}\] WebThe term , where is the speed, and is the fuel consumption rate, is called the specific range (= range per unit mass of fuel; S.I. units: m/kg). The specific range can now be determined as though the airplane is in quasi-steady-state flight. Here, a difference between jet and propeller-driven aircraft has to be noticed.
