Hi, I'm designing a system that spray water into air. I'm wondering how I should go finding out the relationship between the flow rate and distance of travel of the water droplet in air. If I am spraying the water going the same direction as the wind, how much would the velocity of the water pick up? About spraying the water at a particular flow rate, is that normally created by the pressure of a pump, if not then what would dictate the flow rate? Sorry those might be badly phrased question, but could anyone point me to a general direction so I can study more on the topic before asking better questions? Thank you.
