SEDIMENTATION According to Brown (1950)‚ sedimentation is the separation of a suspension into a supernatant clear fluid and a rather dense slurry containing a higher concentration of solid. According to Perry ()‚ sedimentation is the partial separation or concentration of suspended solid particles from a liquid by gravity settling. This field may be divided into the functional operations of thickening‚ whose purpose is to increase the concentration of suspended solids in a feed stream; and clarification

Conclusion 80 References 81 Appendix I.A Appendix II.A Appendix II.B Summary There are two parts in this experiment where we shall observe the mechanics of fluid flow in a closed conduit and also to find out the characteristics of a centrifugal pump. In the first part‚ we applied the principle of pressure difference across fittings in a closed conduit to find out the loss coefficients of these fittings.

the fluid or due to the turbulent behaviour of the flow (Sherwin & Horsley‚ 1996). The continuity equation is a form of the conservation of mass‚ applied to flowing fluids. In the flow the mass flow rate of the fluid entering and leaving the system must be the same (Sherwin & Horsley‚ 1996). It states the product of the density‚ area and velocity of a fluid is a constant in each particular case: ρ1A1v1=ρ2A2v2 Bernoulli’s energy equation is the conservation of energy applied to fluids and

EXPERIMENT (4) FLOW MEASUREMENT By: Eng. Motasem M. Abushaban. Eng. Fedaa M. Fayyad. PURPOSE: To study some of the famous instruments used in flow measurements. The measurement of water flow rate is an important topic in the study of fluid dynamics. There are many instruments used in flow measurements such as : o Venturi o Orifice plate o Variable area meter DESCRIPTION OF APPARATUS Water Flow Measuring Apparatus is designed as a free-standing apparatus for use on the Hydraulics

vaporization or surface tensions are examples of attractive forces. This is the Newton’s law of viscous flow: dfx / dA = η (∂vx /∂z)z Fluids that behave like the equation above are called Newtonian fluids or they go laminar flow. Viscosity coefficient η =kg m-1 s-1 Viscosity measurement is important in many applications. This property of the fluid can be used to determine the rate of mass transport‚ diffusion or within that liquid when it is to be used as a solvent. These are all fundamental

CENTRIFUGAL PUMPS Introduction A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping. Centrifugal pumps are used for

The boundary layer temperature distribution at a given location on the plate may be approximated as T = 30 + 70 exp ( −y ) where y (in m) is the distance normal to the plate and T is in °C. If thermal conductivity of the fluid is 1.0W/mK‚ the local convective heat transfer coefficient (in W/m2K) at that location will
