What is the coefficient of fluid resistance for water?

  1. Oct 18, 2009 #1
    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.
