Extracted text: The use of a continuous atmospheric gravity separator which is also known as decanter is widely applied in separating immiscible liquids that are having distinct densities. Figure 1 shows a decenter that separates two immiscible liquids (Liquid A and B) in which liquid B having higher density than liquid A. The feed mixture enters the unit at one end of the separating vessel and flows slowly to the other end which eventually cause the mixture to separate itself into two distinct layers. Liquid A and B flow out at the overflow lines to the respective collection tank which are open to atmosphere. For a properly designed decanter and assuming that the frictional resistance to the flow of the liquid is essentially neglig ible, analyze the effect of the density of both liquids to the vertical height of the liquid B (hai & hB2).

You are required to perform the analysis as described in section a) and b) subsequently suggest the design parameters stated above. Finally justify the purpose of having the elevated outlet. Please provide the necessary sketch/diagram to show any point of reference in your work.
