I would like to know if there is an equation to predict the pressure drop in a venturi device using a compressible fluid as the working medium. In particular, I'd like to use this equation to predict the amount of vacuum created for a given $\Delta p$ across the device. Simplifying assumptions can be made, such as equivalent inlet and outlet areas.
