Answer:
3.19 days
Explanation:
<em>Given data :</em>
stream flow rate = 50 kg/min
stream contains ; 0.22% sand by mass
Cross sectional area of filter = 9 m^2
Filter successfully filters out 90% of the input sand by mass
SG = 2.25
thickness of cake formed = 0.25 meters
<u>Determine how long a new filter can be used before replacement </u>
Given that for every 1 minute 5.43*10^-5 m thickness of sand layer(cake) forms on the filter and the replacement of filter is done once the cake thickness = 0.25 meters
To determine the number of days ( X ) before replacing filter we apply the relationship below
5.43 * 10^-5 = 1 min
0.25 m = X
hence ; X = 0.25 / (5.43 * 10^-5 ) = 4604.051 minutes ≈ 3.19 days

Answer:
The simplest differential form of Fick's flux equation for water vapor is
Explanation:
Fick's law has to do with the density of the particles is proportional to their concentration gradient. For this question some assumptions will be taken into account:
-The pipe is considered to be very long and diffusion only occurs in the r direction.
-The reaction is not homogeneous, therefore RA = 0
-The concentration of the component A is constant
-No mixing, only diffusion
Due to the complexity of the terms used in solving the Fick equation, the solution is found in the attached file.
