Greetings to everyone. This year, I will be participating in the High Power Rocketry competition called TEKNOFEST Rocket Competition, which is held in my country. In this competition, a ejection charge is used in which the material and weight data are not given. The only thing I know about this material is the pressure-time graph resulting from the test performed in a closed control volume of 1 liter. For the ground tests, I need grams of FFFG black powder that will give the same value as this graph. I don't know how to calculate it. If you want to participate, here is the competition link (https://www.teknofest.org/en/competitions/competition/31) I am waiting for your help. (Test graph of the material is attached)
