P-v-T diagrams

  • Single phase regions : solid, liquid, vapour
  • 2 phase regions: liquid-vapour, solid-liquid, solid-vapour all in equilibrium
  • Saturation states: states at which a phase change begins or ends…

The state principle

2 independent, intensive, thermodynamic properties are required to fix the state of a simple compressible system.

For example,

  • pressure (P) and specific volume (v)
  • temperature (T) and specific internal energy (u)

Cycle analysis

Delta E = Q – W

For a cycle, Delta E=0, so:

Q-W = 0 <=> Qcycle = Wcycle

Power cycles – thermal efficiency

n = Wcycle /Qin… 33 more words


Lose 5-pounds in 5-Days - And Other Gury Tales

The average human arm weights around five pounds. Removal with a band saw could be accomplished in five-minutes, allotting time for vomiting and passing out, so in about five minutes you could drop five pounds and be ready for summer. 1,176 more words

New approach to form non-equilibrium structures

Although most natural and synthetic processes prefer to settle into equilibrium—a state of unchanging balance without potential or energy—it is within the realm of non-equilibrium conditions where new possibilities lie. 441 more words
