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 g c = Unit conversion between D V and
I sp For I sp in lb f -s/lb m and D V in m/s, g c = 9.8...
