QUESTION S
Are many situations in which it is desirable to combine three cycles in series, either power systems or refigertion sytems, to
take advantage of a very wide temperature range or to utilize what would otherwise be waste heat to improve etficiency
O true
O False
QUESTION 6
A cycle can't be made very efficient, since the temperature differences between the two fluid streams can be controlled
through careful design of the combined system.
True
