... 4. The property density “p” is defined as the mass per unit volume. Specific volume “v” is the reciprocal of density; that is, v=I/p. Specific gravity “S” is the ratio of the density of a substance to that of pure water at 40C and 76 cm Hg. 5. Temperature “T” is a property which enables us to determ ...

prediction of improvement of efficiency in a thermal power
... An isentropic process is an idealized process that represents the amount of available energy. The second law of thermodynamics, however, states that the conversion of this thermal energy to useful work cannot be 100% efficient. ...
