A power station with an efficiency of 0.4 generates 108 W of electric power and dissipates 1.5 3 108 J of heat energy each second to the cooling water that flows through it, which increases its temperature by 3 Celsius degrees. Knowing that the specific heat of water in SI units is 4184 J/kg?°C, show that 12,000 kg of warmed water flows through the plant each second.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
