WebNov 30, 2011 · The energy equation in WDN problems is composed of three components in the length dimension: 1. Pressure head (L): ( P / γ ))— P: pressure (pa), γ: water-specific gravity (pa/m) 2. Elevation (L): ( Z) 3. Velocity head (L): ( V2 /2 g )— V: velocity. Then, the energy equation between two nodes is represented as (5.1) where WebThe Energy Equation for Control Volumes. Recall, the First Law of Thermodynamics: where = rate of change of total energy of the system, = rate of heat added to the system, = rate of work done by the system ; In the Reynolds Transport Theorem (R.T.T.), let . So, The left side of the above equation applies to the system, and the right side corresponds to …

WebApr 6, 2024 · The concept of conservation of energy during the flow of a fluid can be explained by Bernoulli's equation. We will find that for a fluid (e.g. air) flowing through a pipe with a constriction in it, the fluid pressure is least at the constriction. In terms of the equation of continuity, the fluid pressure falls with the increase in the speed of ... • P.M. Whelan, M.J. Hodgeson (1978). Essential Principles of Physics (2nd ed.). John Murray.
