Homework Help: Thermal energy power station problem

  1. Feb 19, 2010 #1
    1. The problem statement, all variables and given/known data:
    A power station with an efficiency of 0.3 generates 10^8 W of electric power and dissipates 2.33 multiplied by 10^8 W of thermal energy to the cooling water that flows through it. Knowing the specific heat of water in SI units is 4184 J/kg°C, calculate how many kilograms of water flow through the plant each second if the water is heated through 3 degrees Celsius.



    2. Relevant equation:
    Q=cm* change in temperature



    3. The attempt at a solution:
    2.33*10^8=4184*m*3
    m=(2.33*10^8)/(4.184*3)
