Question

1. looking again at problem 1 how would you define the efficiency of the system? whicch components would you ignore?

2. why does the steam need to be superheated before going into the turbine? what negative effects on the turbine might you expect with insufficient heating? 

3. for the cycle above, how would you need to modify the cycle to accomodate a lower temperature in the storage layer?
