Wiley & Sons, 1941, QC311K26 1970 Science library Keenan's definition: the maximum work which can result from interaction of system and medium when only cyclic changes occur in external things except for the rise of a weight. page 290 medium: environment, atmosphere of infinite extent in which system operates;- in most stable state- all parts at rest relative to each other- homogeneous in temperature and composition- uniform in pressure at any height in gravitational field to be shown: Availability = ( E + p V T S ) ( E + p V T S ) o o o o o o o system at energy E, volume V and entropy S p o , T o pressure and temperature of medium (and of system at dead state - no more possibility of obtaining work) E o , V o , S o ; energy, volume and entropy of system in dead state first show when exchange of heat can occur between system and medium only, the maximum amount of work...
