Actually I want to ask about the work. By my last post's calculations I would need to expel 230gal of air at 130psi to achieve that acceleration. But the work required produce that force over the resulting distance is easily achieved by very small tanks that would not expel 230gal of air. So now...
Thank for your help so far. My research has led me to this thread:

Is the equation for mass flow rate, shown here, appropriate? Because by combining that with the general thrust equation here...
The tank will be stationary relative to the prop. It would function like a rotating sprinkler. Except with a tank of air rather than an infinite source.
Oh, my bad. I was referring to a jet engine like that of an airplane. That type of propulsion would be dependant on its surroundings. But would mine? It functions like a rocket insofar as the work is done by expelling a fuel.
Thank you for the input. I'm not sure that applies here though. I understand that a jet engine would rely on the relative velocity, because it has to accelerate the air around it. But my rig will have compressed air shooting out from within the system. Wouldn't that only concern the actual...
What I'm making is kind of like a sprinkler or Aeolipile. I have a 2 blade propeller that I'd like to boost with an air tank(s). It has to go from 100rpm to 300rpm via a nozzle at the tips of blades. I'm trying to determine the minimum pressure and volume requirements for a tank of air that can...
