consider the following information for a rectangular primary clarifier

a)determine the required surface area(m^2),tank volume(m^3) and detention time (hrs) under both the average flow conditions and peak flow conditions

b) calculate and compare the scour velocity (m/s) and peak flow horizontal velocity (m/s)

Based on these two values,do you expect the particles to re-suspend during the clarification process.

No of rectangular clarifiers=2

Qaverage=20,000m^3/d

Qpeak=50,000m^3/d

channel width =6m

side water depth=4m

overflow rate at average flow=40m^3/m^2.d

density of water=1000kh/m^3

density of particle=1250kg/m^4

beta=0.05m

diameter of particle=200x10^-3m

g=9.81m/s^2

darcy=weisbach friction factor(f)=0.03
