How to calculate the water stream reach in X & Y directions
(OP)
Hi every body,
I am working in the Fire Protection feiled and I wont to know how to calculate the water stream reach comeing out from a nozzle of known diameter.

Go to http://library.thinkquest.org/2779/ for a nice interactive explanation.
The standard equations, given in the web page, apply for a single dimension. You need to apply them according to your particular application and factor them into two horizontal directions (with acceleration = 0) and vertical, (with acceleration = -g) according to the initial angle of the hose and the spread produced by the nozzle. The rest is just math. I am supposing that you already have the data for exit velocity.
This will give you a "close" result, probably as close as you need. If you really have to be incredibly scientific then the droplet size and a whole bunch of other complications come into play.
