Notes / Limitations

  • ASSUMPTIONFluid is homogeneous and density is uniform across the cross-section and time-invariant.
  • ASSUMPTIONNo chemical reaction or phase change occurs within the control volume.
  • LIMITATIONDoes not account for compressibility effects; accuracy degrades for gases undergoing significant pressure drop or temperature change.
  • LIMITATIONNot applicable to two-phase (e.g., steam-water mixture) or multiphase flows.
  • LIMITATIONAssumes steady-state conditions; unsuitable for transient or pulsating flow analysis.
