Note that the initial rocket mass, M 0 , is the sum of the propellant mass expelled during the burn, M p , and the final mass of the rocket after the burn, M b . The resulting equation, known as the "Rocket Equation," is: THE ROCKET EQUATION M 0 / M b = EXP( D V / g c • I sp ) M p = M 0 - M b M 0 = Initial (''wet'') mass M b = Final burnout (''dry'') mass D V = Velocity change I sp = Specific Impulse I sp = F / M-Dot = Thrust / Propellant mass flow rate I sp = lb f -s/lb m or N-s/kg = m/s...
