Depends on what information you are starting with. But generally a properly sized cooling tower is designed to cool water to within 5 degrees of wet bulb temperature.
lbs of water per hour cooled x temperature change in degrees F = BTU's/ hr cooling capacity.
12,000 BTU's/ Hr = 1 TonR tons of refrigeration.

Cooling tower capacity involves inlet water temperature, outlet water temperature, ambient air temperature, relative humidity (wet bulb temp), cooling tower size, air circulation rate and tower fill efficiency. Use this "cooling tower performance calculations" to do a web search and you will find lots of sites that address this somewhat complex subject.

how to calculate capacity of cooling tower in nuclear power plant

If you know the water flow entering the cooling tower and if you know temperature of the entering water and the leaving water, then the amount of cooling is:
Q, Btu/hr = (water flow, lbs/hr)(ΔT, °F)(sp.ht.)
where:
ΔT = T entering - T leaving
sp.ht. = specific heat of water = 1 Btu/lb/°F
If you don't know the water flow rate, you will have to either measure it or find the design specifications of the tower or contact the original manufacturer.

there are two capacities of cooling tower
capacity in term of rate of evaporation,
E=m dtxcp/hv wher
cp=4.186kj/kg
Hv=2260kj/kg
dt.temp difference of entering and leaving water
putting dummy values
4700x8x4.186/2260
=69609 kg/hr
69.609 ton /hr
