i search an formal to calculate the new flow rate on my dolphin orifice when i dive with any trimix instead with nitrox.

Getting back to the original question:

The flow rate of pure helium compared to pure nitrogen is only 5% different-not really enough to make a difference when calculating the fHe fO2 and fN2 of the loop compared to the cylinder.
