Answer to Question 1

Measure the system temperature rise.
Look up the system Btuh output capacity.
Use the formula CFM = Btuh / 1.08 x Temp Rise

Answer to Question 2

A condition known as reverse flow can occur if unequal acetylene and oxygen pressures are allowed to mix in the hoses, regulators, or cylinders. In a worst case scenario, reverse flow can result in a catastrophic explosion.
