What infomation are needed to calculate fps for an air canon? Answered
I know that fps is speed unit, and I'm trying to calculate the initial speed(or the power) for my air canon. Information I have: 1: value of the air chamber 2: psi 3: diameter of the barrel 4: length of the barrel 5: diameter of the air release valve will those information be enough? How to calculate fps or power from information above?
