Introduction The purpose of this lab is to determine: the coefficient of friction between a rubber stopper and a wooden ramp the coefficient of static friction between a wooden block and a wooden ramp the coefficient of kinetic friction between a wooden block and a wooden ramp The design of this experiment was done by placing a rubber stopper / wooden block onto a wooden ramp and tilting the ramp at a certain degree to cause the stopper / block to move. The measurements of the vertical distance

THE EARLY HISTORY OF PVC PIPE By Robert Walker‚ P.E. Uni-Bell PVC Pipe Association (Published in Summer 1990 Edition of the Uni-Bell PVC Pipe News) “Many of you have expressed a curiosity about the historical development of PVC pipe. In response to your requests‚ we provide you with this brief early history of PVC pipe and fittings. PVC was discovered as early as 1835‚ but the first definite report of the polymerization of vinyl chloride did not come until about 35 years later. At that

These false images can either be externally imposed or internally fabricated. In either case‚ one must have the courage to look through this ignorance so that ones true self can be exposed. After reading Mirrors it was obvious that‚ Lucy Grealy cared what others thought about her physical appearance. In time‚ however

have chosen to talk to you about friction. Friction is the force between two objects in contact with each other‚ making it a contact force. It causes moving objects to slow down. Air resistance is a type of friction. Friction is an important force in our lives. We rely on friction in many ways. An athlete usually wears shoes which provide him/her with a greater friction between the shoe and the surface. We rely on friction as an important aspect of motion. Friction can be a very useful force because

Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

Chapter 8 Flow in Pipes 8-76E Solution The flow rate through a piping system between a river and a storage tank is given. The power input to the pump is to be determined. Assumptions 1 The flow is steady and incompressible. 2 The entrance effects are negligible‚ and thus the flow is fully developed. 3 The flow is turbulent so that the tabulated value of the loss coefficients can be used (to be verified). 4 The elevation difference between the free surfaces of the tank and the river remains constant

objective : 1. To determine the head loss and friction factor for laminar & turbulent flow in a smooth pipe over a range of Reynolds’s number . 2. To obtain the following relationships : a. Head loss as a function of the velocity of flow . b. Friction factor as a function of Reynolds number . Theory : The friction resistance to the flow of fluid through a pipe results in a loss of pressure energy for a given fluid flowing a long a given pipe‚ experiments show that for laminar flow : Hl

Fluid Mechanics CHE2161/MEC2404 Frictional Flow in Pipes Experiment : Friday 8.30-11.30am Conducted In : Fluid Mechanics Lab Abstract The main aim of this experiment was to show how the friction factor varies with Reynolds number by manipulating the flow rate of the fluid in a pipe. The main principle used in the experiment was the Bernoulli’s equation‚ taking major head losses into account. These major head losses were normally due to wall friction in the pipe and viscous

Pipe Flow Experiment Purpose The purpose of the experiment is providing an opportunity to students of experience to familiarize with some key aspects of fluid flow in pipe‚ notably friction losses and verify theory. In this experiment‚ required equipment are a water tank‚ piezometric tubes‚ pump‚ a stop watch‚ empty bucket and a digital weight scale. By operating the pump to keep the water is full in the water
