Question

A certain power plant puts out 520MW of electric power.Estimate the heat discharged per second, assuming that the plant has an efficiency of 34%

Answer 1

One MW (megawatt) is 1 million watts.
One watt is 1 joule / second.

If the plant efficiency is 34%, it means that 34% of the energy is converted into electricity, while (100-34)=66% is dissipated as heat.

So calculate the power converted to heat, and use the conversions above to find the heat dissipated in joules per second.
