In this project, the goal is to apply the knowledge of fluid dynamics in order to determine the effect of two parameters (oil density and volume fraction) on how long will it take for an oil drop to rise a distance of 1m in an oil/water distribution.

In this part, the goal was to determine the effect of volume fraction on separation time. In order to determine the effect of volume fraction on settle-time, the density of oil was assumed to be constant with an average value of 900 kg/m3. Volume fraction was varied from a value of 0 to 0.5 and by using the Zigrang-Sylvester relationships provided by the instructor, the coefficients a,b and c were calculated. The settling velocity Uϕ was then determined by using the following relationship;

Uϕ = c – (c2 – a2)1/2

Finally, the time was determined for the oil drops to rise by a distance of 1m by using the following relationship;

Timesettle = Distance / Uϕ

Part 2:

In the 2nd part of the problem, the density of the oil drops was varied between 850 kg/m3 to 950 kg/m3 in order to determine the effect of varying oil density on settling time....

...1. Using diagrams and/or graphs, explain the following terms:
a. Pressure Head
pressure head [′presh·ər ‚hed]
(fluidmechanics)
Also known as head.
The height of a column of fluid necessary to develop a specific pressure.
The pressure of water at a given point in a pipe arising from the pressure in it.
b. Total Discharge Head
Total discharge head refers to the actual physical difference in height between the liquid level in the pit and the highest...

...Fluidmechanics is the branch of physics that studies fluids (liquids, gases, and plasmas) and the forces on them. Fluidmechanics can be divided into
1) fluid statics, the study of fluids at rest;
2) fluid kinematics, the study of fluids in motion;
3) fluid dynamics, the study of the effect of forces on fluid motion....

...WHAT IS FLUIDMECHANICS ?
FLUIED:
Any thing whose particles can move easily from one place to another that means shape can be easily changed upon the application of negligible force.
MECHANICS:
Study of response of bodies upon the application of force.
FLUIDMECHANICS :
Fluidmechanics may be defined...

...An oilspill can be defined as an accidental or deliberate dumping of oil or petroleum products into the ocean and its coastal waters, bays, and harbors, or onto land, or into rivers or lakes (Holum 1977). Between one and ten million metric tons (one metric ton is 1000 kilograms) of oil are put into the oceans every year. The oil is released, most often, in small yet consistent doses from tankers, industry, or on shore...

In every day life, we recognise three states of matter, Solid, Liquids and Gas. Although different in many respects, liquids and gases have a common characteristic in which they differ from solids; they are fluids, lacking the ability of solids to offer...
