Paper Details

A piston/cylinder arrangement has a load on the piston so it maintains constant pressure. It contains 1 kg of steam at 500 kPa, 50% quality. Heat from a reservoir at 700?C brings the steam to 600?C. Find the second-law efficiency for this process. Note that no formula is given for this particular case so determine a reasonable expression for it.
