What is the coefficient of fluid resistance for water?

Click For Summary
SUMMARY

The accepted value of the drag coefficient for a sphere in water is approximately 0.47. This coefficient varies based on flow characteristics, including whether the flow is turbulent or laminar, and whether the fluid is Newtonian or non-Newtonian. The discussion emphasizes the importance of these factors in accurately determining the drag coefficient for experimental comparisons.

PREREQUISITES
  • Understanding of fluid dynamics concepts
  • Familiarity with drag coefficients
  • Knowledge of flow characteristics (turbulent vs. laminar)
  • Basic principles of Newtonian and non-Newtonian fluids
NEXT STEPS
  • Research the effects of flow characteristics on drag coefficients
  • Study the differences between Newtonian and non-Newtonian fluids
  • Explore experimental methods for measuring drag coefficients
  • Learn about computational fluid dynamics (CFD) simulations
USEFUL FOR

Engineers, physicists, and researchers involved in fluid dynamics, particularly those conducting experiments related to drag forces and fluid resistance in various flow conditions.

I'm just looking for the accepted value of the coefficient of fluid resistance for water in order to compare it to some experimental values I obtained. However, I've done several Internet searches and have come out empty handed.

Do any of you know or have access to the accepted value?

Oh yes, the object in question is a sphere.

I think you're looking for the drag coefficient. For a sphere, an accepted value is about 0.47, but this value does depend on your flow characteristics (turbulent or laminar, Newtonian or non Newtonian, etc).

For more values, try searching for drag coefficient.
