A nuclear power plant has a core temperature of 5000 K, and a cooling tower
temperature of 373 K, and is able to produce 1.21 gigawatts of
power. Assume that the plant operates at its maximum efficiency [Carnot efficiency].

giga = 10^{9}
1 watt = 1 J/s
the Latent Heat of Vaporization (L_{V}) of water is 2.26×10^{6} J/kg

How much water is evaporated per second at the cooling towers?
