GMC Typhoon with WIS : Amount of water needed ?

[Roger G.]

One more question arose today :

The system needs 3 bars of pressure differential to be able to atomize the water properly. With boost of 1.3 bars, the pump must provide 4.3 bars. But with two 0.6mm the pressure drops down to about 3.5 bars, right ?This may result in not fully atomized water as the pressure differential is only 2.2 bars. Will an accumulator be fine enough or is a second or a primer pump necessary ?

Thank, Roger
