So there's a disagreement on the forums about whether the piping of rocket fuel in a circular direction before use would cause rotation in the launch stack.
1 side says the cumulative mass of fuel piped in a circular fashion before being expelled would cause an equal and opposite reaction in the launcher.
The other says that the only source of torque would be from the initial acceleration of fuel, but since it decelerates on the other side of the pipe, there is no net torque.
What do you think? Weigh in here.
