Calculate the surface overflow rate and the dimensions of a rectangular shaped
sedimentation tank with L : W=5:1, and a depth of 4 m . The flowrate is 4250(m^(3))/() day and
the detention time is 4 hours.
Find the settling velocity of a sand particle with a diameter of 0.008 mm . Calculate the actual
time for this particle to settle in the tanks mentioned in Question 1. How far will this particle
drop if it enters the tank at the top of the water surface? Calculate the percentage removal
of this particle in the tank. What will be the particle size (diameter) which will be removed
100%\rho _(p)=2600k(g)/(m^(3));\rho _(p)=2600k(g)/(m^(3));\mu =1\times 10^(-3)k(g)/(m).s U_(t)=((\rho _(p)-\rho _(w))gd_(p)^(2))/(18\mu )
A sample of water has the following concentration of ions:
Calculate the total Ca and Mg hardness in me(q)/( L) and as m(g)/(L)CaCO_(3).
Given: Atomic masses -Ca=40(g)/(m)ol;Mg=24.3(g)/(m)ol;C=12(g)/(m)ol;0=16(g)/(m)ol
