SUMMARY

This discussion focuses on the behavior of inviscid and viscous fluids in terms of energy, momentum, and entropy as they fall from a height, specifically in the context of a dam. The user seeks clarification on how these properties change at various stages: at the top of the dam, during the fall, upon impact, and after the drop. The confusion arises from the simultaneous mention of "inviscid" and "viscous," which are fundamentally different fluid characteristics. Understanding these differences is crucial for analyzing fluid dynamics in practical applications.

PREREQUISITES
  • Fluid dynamics principles, including Bernoulli's equation
  • Understanding of viscous vs. inviscid flow characteristics
  • Knowledge of energy conservation in fluid systems
  • Familiarity with entropy concepts in thermodynamics
NEXT STEPS
  • Study Bernoulli's equation for inviscid flow analysis
  • Explore the Navier-Stokes equations for viscous fluid behavior
  • Research energy loss mechanisms in fluid flows
  • Examine entropy changes in compressible vs. incompressible fluids
USEFUL FOR

Students and professionals in fluid mechanics, engineers working on hydraulic systems, and anyone interested in the thermodynamic properties of fluids in motion.

Hello there ,

could you please explain to me what would happen to an inviscid/viscous incompressible flow (energy,momentum and entropy wise)falling from a height ? ( i.e a dam )


Thanks;)

To be honest, I am not really sure what you are asking, especially since you say "invsicid/viscous", which are opposite terms.
 
I meant how would each of the mentioned values ( entropy , momentum , energy ) would change for both a viscous and an inviscid fluid for each phase : a ) at the top of the dam , b) while falling c) when it drops d) after the drop
