Whilst not totally correct (and the equations have nothing to do with actually getting a waterspray system to work effectively) wind flow would just increase the efficiency. The equation is a simplified one for an evaporative air conditioning system, where there is air flow. (It has also been far too long since I've looked at that stuff so I'm probably wrong!)

The main thing for everyone reading to look at is that dumping water onto an intercooler is not the most efficient method for reducing intake temps. It is effective, but more efficient methods as mentioned (i.e. copying OEM) can be implemented.
