If a 1.0 m3/s flow water treatment plant uses 10 sedimentation basins with an overflow rate of 15 m3/day.m2 ,
a-what should be the surface area (m2) of each tank?( i got this part right the answer is 567 m2)
b-Do the problem again but for an alum or iron floc with an overflow rate 20 m3/day.m2?
Lines of levels were run requiring n instrument setups. If the rod reading for each backsight and foresight has a standard deviation δ what is the standard deviation in each of the following level lines?
