What is the sedimentation rate in a suspension?
THIS IS THE COMPLETE QUESTION; it's just the approximately sedimentation rate in a suspension, not a solving problem.
a. 10^-5 m/s
b. 10^-2 m/s
c. 10^2 m/s
d. 10^5 m/s
I would think 10^-5
Homework Answers
Sedimentation and suspension depend on a variety of factors
-
1. Viscosity
2. Mean particle size
3. pH
4. Density of external phases involved
4. Reactions occuring, if any
Now, the increment in viscosity and density can decrease
settling/sedimentation rate, while increasing particle size can
increase sedimentation. pH and reactions, are dependent on the
substances involved.
For a general case, sedimentation follows b. 10-2 m/s, i.e. around 1 cm/s for a particle flow to go down.

Problem 2 (20 points) You are hired to design a rectangular sedimentation tank (length to width ratio = 3:1 and detention time 2 h) for a new water treatment plant (flow rate: 0.04 m/s; temperature: 20 °C). Suspended particles can be removed when the overflow rate is higher than the settling velocities of particles.

mitochondrial suspension. Here's what my hypothesis is: An
increased amount of the substrate succinate will increase the rate
of cellular respiration.

reaction. But that was not what my graph showed. Here is what was

A water treatment plant is processing water at a flow rate of 1.5 m/s using three parallel treatment trains. The detention times for the rapid mix tank, flocculation basin, and rectangular sedimentation basin are 10 sec, 30 min and 60 min, respectively. The velocity gradients for the rapid mix and flocculation tanks are 900 s and 60:40:20 s1, respectively. The viscosity of water is 0.001 Pa-s. (a) Determine the size and power requirements for rapid mix tanks. (b) Determine the...

Flocculation tanks need to be sized to match three sedimentation basins 3.5 m deep and 6.0 m wide. The sedimentation basins each handle a flow of 5000 m/d, as will the flocculation tanks. The floc tanks will have two mixing sections with an overall average velocity gradient (G) of 35/s. The average velocity gradient-time (Gt) value has been set at 80,000.
