(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.

You can try CAEFLOW provided by SST Systems, Inc. Go to the web site www.sstusa.com, and download a free evaluation copy of that.
Hope it helps.

RE: How to calculate the water stream reach in X & Y directions

I think that this has to be solved using standard equations of motion relating distance, speed and acceleration.
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.
