4.12. Velocity and time of terminal sedimentation. a particle of 1.0 m and density of 1.06 g/cm3 settles in water of density 1.00 g/cm3 and viscosity of 0.01 g/cms. It is requested: a) Calculate the terminal velocity of the particle. b) Obtain an expression for the time it takes the particle to reach 99% of its terminal velocity (t99). c) Calculate the time t99. d) Obtain an expression to calculate the distance traveled by the particle at the moment of reaching 99% of its terminal velocity (x99). e) Calculate x99
