What can we observe during the cake filtration of suspensions?
Homework Answers
Cake filtration is the process of passing solid suspension (commonly known as slurry) through a porous media. It is done to seperate the solid particulates from the suspension. Solid particles are retained on the porous medium(also known as septum).
During filtration process initially solids that are trapped in the pores of medium forms the true filter medium. As the time proceeds thickness of cake( solid reatined on spetum) increases, this in turn decreases the rate of filtration which also increases the resistance across the cake.

What is the standard deviation of the X bar? Can we observe the σ in the formula? What do we use in place of the sample standard deviation? That is sd of N observations? (it should be in square root because it’s the sd!)

4. A suspension of yeast cells is to be filtered at a constant filtration rate of 50 L/min. The suspension has a solid content of 70 kg/m3 of suspension and the yeast cells have a bulk density of 800 kg/m3. Laboratory tests indicate that the specific cake resistance is 40 m/kg and the viscosity of the filtrate is 2.9x10-3 kg/m.s. The filter has an area of 0.1 m2 and the medium offers negligible resistance. How long can the filtration rate...

From Irvine, we observe that the North Star (Polaris) is located at an elevation of roughly 33 degrees. We then quickly fly north 1600 kilometers to Seattle, where we observe Polaris to be at an elevation of 48 degrees. Recognizing that there are 360 degrees in a circle and a circle’s circumference is equal to π × its diameter, what is the approximate size (i.e. radius) of the Earth? [π can be approximated as 3.]
