Please answer all 1. List the three corrections which should be applied to the hydrometer readings. 2. Why is it important to remove the hydrometer from the measuring cylinder between readings? 3. A hydrometer test has the following results; Gs = 2.70, temperature = 240C, and L = 92 mm at 60 minutes after the start of sedimentation. Calculate the diameter of the smallest-size particles that have settled beyond the zone of measurement at that time (use the table in the lab manual to find, A=0.0128). D(mm) = A sqrt( L(cm) / t(min) )
A water treatment plant processes 21,000 cubic meters of water per day. Assume two types of flocculated particles enter the basin. You are asked to evaluate the performance of a rectangular sedimentation basin that has dimensions of depth=4 m, width= 6 m, and length= 40 m. The first type of particles has a settling velocity of 0.5 m/hr and the other type has a settling velocity of 1.8 m/hr. What percent of particles are removed for each of the two types of particles?
