From this, it follows that: - The attainable pressure ratio is not a function of speed. Therefore, high pressure ratios are possible even at low speeds and thus small volumetric flows. - The volume flow rate V_ 1 is practically only a function of speed. - The map is stable in the entire region and consequently usable for supercharging.
