Hey I want to build a pneumatic arm that can throw stuff around (see attachment image). Before actually ordering the stuff i want help with some calculations. i want the arm to be able to push 5kg load (rectangular shaped) straight up into air. the arm/plunger area that makes contact with load = 0.0050m^2 i want this arm to throw the load to atleast 10 metres off the ground. How much force/pressure would that require ?
