SUMMARY

The discussion centers on the correct formula for viscosity, specifically addressing the misconception that viscosity can be expressed as (mass x length) / (time x area). Participants clarify that the appropriate unit for viscosity is mass / (length x time), emphasizing that the dimensions of viscosity must reflect its definition as a measure of resistance to flow. This distinction is critical for accurate scientific communication and understanding of fluid dynamics.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with dimensional analysis
  • Knowledge of viscosity and its physical significance
  • Basic physics concepts related to force and motion
NEXT STEPS
  • Research the definition and units of viscosity in detail
  • Explore dimensional analysis techniques in physics
  • Learn about the applications of viscosity in fluid mechanics
  • Investigate common misconceptions in physics formulas
USEFUL FOR

Students studying physics, particularly those focusing on fluid dynamics, educators teaching viscosity concepts, and anyone interested in the mathematical foundations of physical properties of fluids.

You are asking about the units of viscosity, but, at least to me, your question does not make sense. What exactly are you asking?

i don't agree with the formula mass/ (length x area)

i think it is wrong

The units should be mass/(length x time)
