My apologies if this has been covered before: I didn't find it in a quick search, so here goes. What is the equation for the power required to drive a supercharger? For example, how much power is required to supply 700 cfm of STP air at one atmosphere of boost? Assume 100% efficiency for the moment. I'm designing a drive system and want to get in the right ball park for the torque required of the drive for various systems. Thanks!
