Hey everyone, so I'm just wondering if you guys can articulate the term "velocity of lost mass" from the rocket. After a few massaging on the equations(derivatives and integrals stuff) i found that to manipulate the thrust, one must manipulate the burn rate AND the "velocity of loss mass". all i know about the velocity of loss mass is that it's well the velocity of the mass that's being exhausted from the rocket itself. So my question is: How could you experimentally calculate the velocity of lost mass(notes: this is not the burn rate but the speed of the mass that's being exhausted)
These are the equation if you wondered:
F=(dm/dt)u (u is the velocity of lost mass)
or this:
