Homework Statement
Consider a cryogenic chemical propulsion system with Isp (specific impulse) = 450 s
Enter the required propellant fraction as a proportion with at least two decimal places.
The ΔVelocity is provided. ΔV = 9.6 km/s
Homework Equations
Rocket equation:
ΔV = Vex x Ln (initial mass/final mass)
The Attempt at a Solution
I'm atrocious at math, yet this question has come may way nonetheless. Do I just reverse the standard rocket equation one uses to find the Delta Velocity?
Propellant/final mass = ΔV x Isp?
I need smart folk.
