    Friction Losses Abstract—The purpose of the experiment is to study the differences of roughness‚ valves and geometries of pipe and how they influence friction losses. Introduction Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipe. This energy drop is dependent on the wall shear stress (τ) between the fluid and pipe surface. The shear stress of a flow is also dependent on whether the flow is turbulent

    joints‚ which means that they have a cavity in the joints that contains synovial fluid. Joints are not just made of bone‚ because if they were‚ friction would keep them from moving smoothly. The body uses cartilage and the synovial fluid to reduce friction in joints. Osteoarthritis happens when cartilage wears away over time and exposes bone to bone and increases friction‚ which is very painful. Synovial fluid is a fluid-like material that is present in many of the joints of the body. It serves the

    Lab Report: Pipe Friction MODULE LEADER: Dr. MEHDI NAZARINIA 1. Introduction The flow of fluid in a pipe under pressure is used to reach many goals. A good knowledge of the fluid flow and pipe pressure at some point along the path of the pipe may facilitate to determine the size‚ capacity and material of the pipe for a system. In engineering and industry‚ the understanding of pipe flow is required for the control‚ transport‚ measure and storage of water or other fluids.

    Friction Cynthia Clark Student No. xxxxx May 19‚ 2009 Abstract This experiment measures the coefficient of static friction (μs) and kinetic friction (μk) between objects of different materials. Friction is a force that must be overcome before an object can move across a surface. A plain block of wood and a block of wood with sandpaper on one side and glass on the other were used. All of the blocks had a soup can with a mass of 0.41

    Hypothesis: For an increase in a normal force‚ there will be a corresponding increase in friction. Introduction: Force is usually connected with a push or pull exerted on an object. In this experiment‚ I am using a contact force‚ a force that exists from physical contact between two things. I am pulling the spring scale‚ which measure force in Newtons (kg x m/s2)‚ and then the block is moving. Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due

    Purpose/Problem/Question Which type of friction is the largest force – static‚ sliding‚ or rolling? Which is the smallest? II. Background Information From our previous activities that we did in class‚ I know that static friction is a very large force. The force is larger than rolling‚ sliding‚ and fluid friction. I also learned that rolling friction is the smallest type of force. This information may connect to my final analysis. III. Hypothesis If static friction is the largest force‚ then either

    Fluid Mechanics Report Instruction Water turbine is a very common used throughout the world to generate power. Although the concept of the Impact of a Jet is essentially simple‚ and it can has a highly hydraulic efficiency‚ the factor of how can produce a powerful reaction force back is also has to be considerate truly. If we can manage well‚ we can determine the best situation and the optimum deflection angle out‚ for getting the optimum force that the impact can produce. But first of all‚ we
