Re: Help Calculating time to recharge air tanks

I don't think you're accounting for the lower flow rate at higher pressures. If you plot how long it takes to make each 10psi increment you'll find that the higher ones take a lot longer.

Your experimental value of 20 seconds to run from 60 to 120 psi sounds close to what our experience has been in the past. Unfortunately we're not using pneumatics this year so I can't easily get you a comparison value.

Hint for your compressor testing: put a fan on the heat sink. The approved compressors have a very low duty cycle and it's easy to overrun it during tests.
