Summary

Head Loss Fluid Mechanics Introduction Fluid flowing in pipes is usually turbulent. The flow is considered turbulent if the Reynolds value is greater than 4000. During the turbulent flow, the velocity distribution is relatively the same (or uniform) and the velocity profile is flatter in comparison to the laminar flow…

Head Loss Fluid Mechanics

Fluid flowing through a pipe encounters resistance because of resistance offered by the pipeline, viscosity of the fluid, and the roughness present in the pipeline’s interior surface. The main energy loss in a pipeline is because of friction as the pipeline has usually long length (Sawhney 2011, p629). The pipeline’s total energy decreases based on the direction of the flow. Fluid flowing through a pipe encounters resistance because of the resistance offered by the pipefittings, fluid viscosity, and the roughness present in the pipeline’s interior surface. Turbulence is generated in fluid flow because of resistance leading to loss of pressure and energy head (Sawhney 2011, p630). The decline in fluid flow energy (generally expressed as units of feet) as the fluid flows through the system is referred to as head loss (Wolf Creek Nuclear Operating Corporation 2004, p2). Head loss in pipeline can be variable head loss due to changing cross-section and constant velocity head loss. The constant velocity head loss occurs because of the kinetic energy loss as the fluid flows out of the pipeline having some velocity at the exit and due to the friction in the pipe. ...

From the chart we have D10 = 0.2 D30 = 0.45 D60 = 1.20 So Coefficient of uniformity is = D60/D30 Cu = 1.20/0.2 = 6.0 And Coefficient of curvature of the soil is = D302/(D10 x D60) Cc = 0.452/(0.2 x 1.2) = 0.84375 (iv) From the particle size distribution chart we can see that the particles are distributed over a wide range. So, this is a well graded soil.

. 30 Task 1 Laminar flow Laminar flow is a type of flow where fluids generally move at low velocity. The layers of the fluid slide by one another. There is no lateral mixing of the fluid and no formation of eddies, cross current or any swirls. Particles of the fluid move in straight line in orderly manner parallel to the boundary walls which can be seen in straight sections of pipes. It generally occurs at a Reynolds number below critical value of 2040. Turbulent flow Turbulent flow is a type of flow that occurs in large velocities characterized with the formation of eddies, swirls and other…

Soil Mechanics (Geotechnics
Soil is composed of particles such as silt, clay, gravel and sand and they can also contain other gases that exist in between these particles. The study of soil is very important because this is what makes the study of geotechnical engineering possible. This is a subtopic in civil engineering and it is a very complex topic. Soil mechanics is applicable in many ways as far as building and construction is concerned and some of the best examples are such as building foundations of bridges, dams and sustaining systems of buried pipelines. This is very important because it ensures that buildings do…

Experiment 2 There is a slight fall in pressure in the approach section and the static pressure is at a minimum about one pipe diameter before the orifice plate. The pressure of the fluid then rises near the face of the orifice. There is then a sudden fall of pressure as the fluid passes through the orifice, but the minimum pressure is not attained until the vena contracta is reached. Beyond the vena contracta, there is a rapid recovery in the static pressure. Owing to friction and dissipation of energy in turbulence, the maximum downstream pressure is always lesser than the upstream pressure.…

TYPES OF DRAG Form drag This could be described as the frictional force resulting from the shape of a moving object. This drag remains highly dependent on size and shape of objects; hence, the name form drag (Batchelor 2000). Bodies with larger cross-sectional designs experience higher levels of form drag than those presented with sleek design. The shape and size of a body affects the surface area of the object which comes into contact with the fluid. The experienced frictional forces results from contact between the moving object and fluid through which movement occurs. The occurrence of this…

Used to restrict flow through the line. Used to control the velocity of fluid within the piping. Extensively used to measure flow rate within the piping. Orifice in the form of orifice plates is widely used for injecting constant flows to the apparatus. They are vital part of electronic fuel ignition systems where metered amount of fuel is injected within the combustion chamber through orifice, as they provide very stable flow. Orifices used for such critical applications are designed with great effort. They must be smooth enough to reduce frictional effects which greatly affect the efficiency…

the principle ,method and applications of fluid pressure measuring
For example, the pressure at the bottom of a dam is equivalent to the ratio of the weight and the area of the column covered by the water. Fluid pressure can be caused by acceleration, gravity or hydraulic systems those results into force thus affecting static fluid pressure. Fluid pressure applies in all directions hence internal pressure of a fluid is equivalent to the external. In this regard, if either pressure is different (internal or external) the object holding the fluid would break. This principle explains the reasons why dams are always constructed thicker at the bottom. The fluid…
