Homework Statement
A solid sphere - 20mm in diameter, σ (specific gravity) = 1.3
dropped in water μ=1*10^-3 and ρ=1000
determine the terminal velocity for the sphere.
(hint- guess the value for the drag coefficient then iterate)
Homework Equations
Fd=(1/2)*Cd*ρ*(U^2)*A
The Attempt at a Solution
tried guessing the drag coefficient but have no confidence in estimate or of the next step.
(also the relationship equation connecting viscosity, specific gravity and density would be much appreciated).
Thank you in advance for your help.
