Query on Negative Temperature, Internal
... usual temperature T>0; dS<0 if T<0. Further, if T>0 and (dU+PdV)<0, for example, a contractive process is dV<0, dS<0 is possible [6]. In fact, so long as dS<0, the negative-temperature is unnecessary. Otherwise, one of the standard formulations of the second law of thermodynamics must be altered to ...

First, air is a poor conductor of heat so that, for an air parcel of reasonable size (larger than a building), ...

Rankine cycle analysis 5
... The Rankine cycle is the most common of all power generation cycles and is diagrammatically depicted via Figures 1 and 2. The Rankine cycle was devised to make use of the characteristics of water as the working fluid. The cycle begins in a boiler (State 4 in figure 1), where the water is heated unti ...
