    Hi, Charles !

    Hmm . . . A "GRANT" will get you an mid-range "I" reload, if you already have hardware . . . LOL !

    Several of them could probably be wound up tightly and be used as the grain for a hybrid... well, maybe a micro-hybrid (with a 16g N2O cylinder). That would put it in the low-E range...

    im planning to use liquid propellant. So openrocket and rocksim I believe would be almost useless.

    If you can't get OR to sim a liquid, you should not mess with liquids. Note that I am not saying OR is the right tool here.

    Respectfully I suggest you fly commercial solids until you have enough experience to debate the two previous statements.

    +1 to dhbarr.
    If you have the thrust data for this liquid propellant motor, then you can use these simulators. If you don’t have, or can’t measure, the thrust data of this motor, then you won’t be launching it any time soon!

    What propellant ?

    What oxidizer ?

    Cryogenic ?

    Hypergolic ?

    Can you tell us about yourself and your experience and what you want to accomplish?

    This entire conversation doesn't seem proper.

    Personally, I would start with water and work up from there.

    ;)

    Ill admit I am one of those engineers and I see it in my friends as well though I do understand that I don't know everything and as a result I tend to ask a lot of questions, some that may come out like this (though not this extreme). Its just that we are at that age of beginning to truly understand things and we want to push the boundaries.

    Final answer to the original question. You will need 1 lb more than the weight of rocket in total thrust of the rocket to meet any altitude requirement you desire.
