(OP)
hallow everyone,
do any one have an idea how i can calculate or estimate  pressure drop of water flow  in a full cone nozle  sprayer outlet of a wet cooling tower?Any helpful fomular will be appreciated.

Get the catalog from the manufacturer of the nozzle.

Good luck,

Or, go to their website.

Martino6000, I think you already have a good idea of the pressure drop.  It is pressure upstream of nozzle minus atmospheric pressure.  Put a pressure gauge on the cooling- water return-line, subtract any additional pressure decrease due to the height of the nozzle vs where you measured the pressure, and then subtract 1-2 more psi for frictional losses (depends on how far away from the nozzle you are), and there is your nozzle inlet pressure.

Nozzle manufacturers rate their nozzle flow characteristics basis the available pressure drop in a system.  I can't estimate without seeing your system, but other cooling towers I have seen usually have a delta pressure of 15 to 30 psi.
