Hey everyone, I'm building a rocket with my friend from scratch. I have calculated the specific impulse of the rocket engine that we have designed and it turned out to be around 235 newton-seconds. I was wondering what the maximum weight of rocket this engine would get off the ground, and how to figure it out. If you need more information I probably have it I just don't know what information you will need. I'm a grade 11 student and haven't learned this kind of thing in school. Thanks!
