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

Experiment 5: Friction Laboratory Report Charles Sanchez‚ Geminesse Sianghio‚ Ferguie Solis Department of Chemistry College of Science‚ University of Santo Tomas España Street‚ Manila Philippines Abstract In this experiment‚ a block of wood is used to observe friction on different surfaces such that an extra weight is also added to the block of wood to measure the same units under the different surfaces. With also the use of lubircant a member of the group was asked to observe the

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

experiment is to study the friction loss along a pipe. In this experiment‚ water and mercury have been used to demonstrate the law of resistance with different types of flow which are laminar and turbulent flow. The variation of head loss will be obtained and hence determined the Reynold numbers and friction factor. In the end of the experiment‚ the law of resistance which is the relationship between i and u will be determined and hence established the critical R and friction factor. 1.0 Introduction

Pipe Friction Summary The purpose of this lab is to find the friction factor and Reynolds number for laminar and turbulent flow and also for values in the critical zone. Results were taken recorded and used to calculate the friction factor and Reynolds number. They were then compared with the Moody diagram. Aim This lab could be used in industry when dealing with a pipe line containing any type of liquid to calculate the Reynolds number and friction factor. It would also help in pipe

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

COLLEGE OF MEDICAL SCIENCES Physics Lab Experiment Geometrical Optics Name : INTRODUCTION Friction is a force (measured in Newtons) acting along the surfaces of two objects in physical contact that impedes the relative motion of these objects (the motion of one with respect to the other). As such‚ it can be said that friction always acts opposite the motion of the object or the force applied. There are two main types of friction: Static friction: the frictional force that opposes any
