I am planning to use an air compressor to inflate a rubber balloon. I need to size the compressor for inflating the balloon, but for sizing the compressor I need the pressure required to inflate the balloon. So, can anyone guide me to calculate the required pressure for inflating a rubber balloon?
A typical human can exert an over-pressure of ~$9.8kPa$ with their lungs. Given that balloons are designed so that a human can inflate them, I'd say go for a pump that can deliver $10kPa$ of pressure (that's around $1.5psi$ in case you were wondering).
