Calculating the size of a resistor

Why not arrange a variable air leak? Put a tee in the output line,
near the pump, and a little plastic valve on the side arm of the tee
that you can open varying amounts to reduce the amount of air getting to
the output end of the pipe. Doesn't load the motor and can be varied
at will.
I like that. Thank you.
