I'm working on a project involving compressing air to a desired high pressure. So far the only equation I've been paying attention to is the ideal gas law. My question is if an air compressor pump is rated to create a maximum pressure of 100 psi based on its inlet being at atmospheric pressure, does this mean if the inlet is at 100 psi already the pump will be able to raise the outlet pressure to a 200 psi maximum? In other words, is the difference between inlet and outlet pressure the only thing to consider here? It seems too simple that daisy chaining low-cost compressor motors together could achieve incredibly high air pressures. If anyone could explain or drop a link or reference to any good resources which explain the mechanisms at play here I would greatly appreciate it. Thanks!
