Hi guys and girls,
I hope you can help an electronics engineer out of his place in the mechanical world
My very basic question is for a vessel holding a liquid at a given pressure and a given opening in the vessel how can i calculate exit velocity and mass flow rate? Like if i blow a balloon up to say 1 bar (good balloon huh:)) and then put a 1mm hole inside it how fast will the air be travelling as it leaves the balloon?
I dont need anything to detailed ( not worried about internal friction losses etc) and for now i can assume the vessel is fed by constant pressure mechanism i.e it wont drop pressure as it empties!
Any help gratefully recieved
