This problem compares the energy output and heat transfer to the environment by two different types of nuclear power stations—one with the normal efficiency of 35 %, and another with an improved efficiency of 46 %. Suppose both have the same heat transfer into the engine in one day, 2.45 × 1014 J .  Part (a)  How much more electrical energy is produced by the more efficient power station?  Part (b)  What is the change in the heat transfer to the environment after the upgrade to the more efficient power station?

Question

  This problem compares the energy output and heat transfer to the environment by two different types of nuclear power stations—one with the normal efficiency of 35 %, and another with an improved efficiency of 46 %. Suppose both have the same heat transfer into the engine in one day, 2.45 × 1014 J .

 Part (a)  How much more electrical energy is produced by the more efficient power station? 

Part (b)  What is the change in the heat transfer to the environment after the upgrade to the more efficient power station?
