Homework Help: Fluid Mechanics, Renoylds Number

  1. May 3, 2007 #1
    A particle falls in water and reaches its terminal velocity. if the density of the particle is 1100kg/m3, what is the velocity and diameter is Re = 1.0

    Again guys bit lost with this one, there are so many different equations relating to this i dont know where to start. hopefully some one with a bit more experiance can help me.

    Thank you in advance.

    A particle falls under gravity. What is the condition at terminal velocity, i.e. the particle no longer accelerates?


    vs is mean velocity of fluid or velocity of object in fluid.
