...?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. It is important to note that there are pressure fluctuations and irregular velocity in turbulent flow. In turbulent flow, fluctuations in velocity influence the mean motion such that it causes additional shear resistance to the flow. The turbulent shear stress is composed of shear stress and viscous shear stress generated because of turbulence (Sawhney...

...Laboratory Report: Fluid Mechanics— Verification of Bernoulli’s Equation The behavior of the laminar fluid motion along a converging-diverging tube of known cross-sectional area, at different flow rates, is investigated, and the mass as well as energy conservation laws are verified in this experiment. Another objective of performing it is to measure the loss of energy due to viscous resistance to the fluid the motion in case of higher flow rates. The results obtained from the experiment not only verify the basic laws and characteristics of a fluid in motion, but also determines the losses incurred in energy due to resistive forces. Introduction When a...

...?Fluid Mechanics 230 INTRODUCTION Drag could be identified as a resultant forces causing resistance to motion in bodies moving within fluids (Tipler 2004). Unlike other frictional forces experienced in moving objects, drag forces normally remain fully dependent on velocity of objects. These forces have been identified as reducing velocity of objects moving within fluids depending on the size of objects. Various types of drag exist when studying drag resulting from movement of physical bodies within fluids. The different types of drags are as discussed below. TYPES OF DRAG Form drag This could be described as the frictional force resulting from the shape...

...in the construction is factual. But as we can see from the open channel layout map, the elevation from the southern tip of Estwaite Water which is station 0+000 to station 2+000 is constant. But at station 0+030, the channel will have to cross a road. The road elevation is at approximately 67 meters as shown in the map, therefore the channel has to be build under the road crossing or a short bridge so as to give way to the open channel to pass under the bridge or road. Station 0+030 will be considered a critical point in the design, because the velocity of the water passing under the bridge decrease depending on how the bridge would be build. In consideration to the design of most...

...Topic: Hydraulic structures Describe the design and operation of dams and reservoirs indicating the factors affecting choice of dam and reservoir site.
Introduction
Hydraulic structures are basically constructed to direct and manage water flow. The following deals with the design considerations of dams and reservoirs. Dams are constructed to obstruct and divert the natural flow of water. A reservoir is an artificial lake in existence because of dam construction. The construction and operation of these hydraulic structures involves numerous socio-economic factors.

... Laboratory Report: Fluid Mechanics—Bernoulli’s Equation Using the conservation laws of streamline motion of fluid, we investigate the behavior of the fluid motion along a converging-diverging tube of known cross-sectional area, at different flow rates. The energy lost as a result of viscous resistance of the fluid the motion when the flow rate increases, may also be measured as Head Lost.
Introduction
When an incompressible fluid starts moving along streamlines, two basic laws get satisfied. One can use these two laws to check the behaviour of the dynamics of the fluid. Moreover, both these laws pertain to certain conservation of fluid properties—

Water at 50 degrees Celsius flows at a mass flow rate of 20 kg/s in a 200 mm diameter pipeline.
a) Find the density and dynamic viscosity of the water at this temperature
letbe the dynamic viscosity

Human disease, suffering and death are amongst the major concerns of society.Early diagnosis and treatment of disease is one of the indicators of the advancement of civilization. The vascular system of the human body made up of blood vessels carries oxygenated blood from the heart to the different organs, maintains the temperature of the body and removes wastes from each organ. Impairment of blood flow is the major cause of various types of diseases such as heart attacks, strokes, problems of the liver, the kidneys, the stomach and...
