Mass Flow Rate Formula: Concept, Formula, Solved Examples

WebMay 13, 2024 · The amount of thrust produced by the rocket depends on the mass flow rate through the engine, the exit velocity of the exhaust, and the pressure at the nozzle exit. All of these variables depend on the design of the nozzle. ... The hot exhaust flow is choked at the throat, which means that the Mach number is equal to 1.0 in the throat and the ... In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures. Mathematically the discharge coefficient may be related to the mass flow rate of a fluid through …
