Thermodynamic Formula Sheet - Where “below” refers to point at lower elevation and “above” at higher elevation. 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. Definition 2.1.1 — ‘thermodynamical system’ (or ‘system’). Q = heat transferred during the process between state 1 and state 2. = work done during the change from state 1 to state 2. 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. Whatever “macroscopic” part of the universe we select for study. Web variation of pressure with depth: K = specific hear ratio.
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. Q = heat transferred during the process between state 1 and state 2. = work done during the change from state 1 to state 2. Whatever “macroscopic” part of the universe we select for study. W = rate of work = power. K = specific hear ratio. The absolute and gage pressures in a liquid open to the atmosphere at a depth of h from the free surface are: Apply between two points in the same fluid. Q = rate of heat transfer.
