Thermodynamic Formula Sheet - = work done during the change from state 1 to state 2. K = specific hear ratio. Q = heat transferred during the process between state 1 and state 2. Apply between two points in the same fluid. The zeroth law of thermodynamics 2.1 thermodynamical systems before we embark on deriving the laws of thermodynamics, it is necessary to define the main vocabulary we will be using throughout these lectures. W = rate of work = power. Where “below” refers to point at lower elevation and “above” at higher elevation. Web variation of pressure with depth: Definition 2.1.1 — ‘thermodynamical system’ (or ‘system’). Whatever “macroscopic” part of the universe we select for study.

The absolute and gage pressures in a liquid open to the atmosphere at a depth of h from the free surface are: Q = rate of heat transfer.
