1) In order to separate the oils from the water in waste water, the oil-water mixture is given to a settling tank, decanter, (D=0.80 m, L=2.40 m) standing in a horizontal position (T=25°C, atmospheric pressure). The oil ratio in waste water can be considered as 15% (v/v). Here, drops of oil (density: 890 kg /m) are collected in the upper part of the tank, while water drops are collected in the lower part of the tank. For an efficient separation, it is recommended that 65% of the tank height is filled with the water phase and 20% with the separated oil phase. In this case, what should be the height of the water phase outlet pipe (H)? 1) In order to separate the oils from the water in waste water, the oil-water mixture is given to a settling tank, decanter, (D=0.80 m, L=2.40 m) standing in a horizontal position (T=25°C, atmospheric pressure).
