1) A nuclear power plant generates waste thermal energy at a rate of 1000MW=1000*10^6W. Assume the heat of vaporization of a water is 2.256*10^6J/Kg….

1) A nuclear power plant generates waste thermal energy at a rate of 1000MW=1000*10^6W. Assume the heat of vaporization of a water is 2.256*10^6J/Kg.

1a) If this energy is transferred by hot water passing through tubes in the water in an evaporative cooling tower, how much water must evaporate to cool the plant per second?

1b) How much water must evaporate to cool the plant per day?

1) Calculate the net force on your 0.5cm^2 eardrum that air exerts on the inside and the outside after you drive from Denver, Colorado (elevation 1609m) to the top Pikes Peak (elevation 4301m). Assume that the air pressure inside and out are balanced when you leave Denver, the pressure inside the eardrum does not change and that the density of the air is constant and is equal to 0.80kg/m^3. Calculate the magnitude of the net force on the eardrum.
