How much pressure will be generated when liquid oxygen and Kerosene are combusted in Rocket combustion chamber?
I do not exactly work in these things but i will try to give you an idea of how to approach the problem. See you have to find out the heat of combustion of kerosene(keep in mind kerosene is not one compound so you will have multiple equations to solve) and then get the amount of energy released per mole of combustion of kerosene and this will also give you the optimal amount of oxygen you need. Next is the tricky part and i know people who regularly loose hair over this..:) You have to assume the density of gases @ STP after the combustion of kerosene. Given that you have to find out the optimal chamber size and nozzle size depending on the pressure and temperature. The way you do this is assume that almost 80-90% of the energy released is transmitted to the gases and this causes them to heat and expand and increase pressure in turn causing a certain amount to leak out of the nozzle (pascals law and law of thermodynamics will be needed here), to maintain a certain pressure (thrust) you
