Simple math question

[jlkingiii]

I have been playing with Orbiter for about three weeks now and am just starting to play with the math. I haven't done any math since college which was about ten years ago, so be gentle. And I hope I am asking the question correctly.

What I want to calculate is the amount of fuel burned in kg/s from the MaxAttitudeRotAccel in the cfg file. I want to keep this simple for now until I understand the concept behind it. So for simplicity let's assume that the mass is constant and does not reduce as the fuel burns. In general terms what is this equation?

Oh I guess for clarity I should mention that I am talking about rotational movement and not linear.
