Calculating Propellant Mass by Piper (Orbiter Forum)

Calculating Propellant Needed for a maneuver:

P = Me * Exp(Δv / Ve) - Me

Equation Explained

• P = Propellant needed in kilograms.

• Me: Empty mass of the rocket at burnout with all propellant expended in kilograms.

• Δv = Delta-vee) of the manouver in meters per second.

• Ve: Velocity of the rocket's exhaust in meters per second.
