[Unified-mailman] T7

[Ian Waitz]

Unified students,

>Just a quick question: Does it matter what type of cycle we consider the heat

>temperature difference between the respective reservoirs seems important, but
>the relation between these temperature differences and the heat transfers and

For T7 part b), please assume a Carnot cycle as in part a).

[Note also, I am still uncertain relative to the status of the Cogen 
website.  I will keep you posted.  If it doesn't get sorted out soon, 
I will extend the due date for T9.]

Best wishes,

- Ian
