Prelab problem: In this experiment, you will apply a horizontal force to a box lab journal (label axes with quantities plotted and units) and give the results of the
The transitional regime between laminar and turbulent flow will also be studied. The experiment was done using a pipe with a known diameter, and water was pumped in from a tank. TA: Li Yabo Friction Lab Report # 3. Introduction: Friction is a force which happens as a reaction of force and it can be stated as it opposes the motion of the actual force. There are two kinds of friction forces, static and kinetic forces. near the fittings. For a long pipeline, on the other hand, skin friction at the pipe wall will predominate.
Use the template provided to prepare your lab report for this experiment. Your report should include the following: Table(s) of raw data; Table(s) of results; Graph(s) On one graph, plot the experimental and theoretical values of the friction factor, f (y-axis) against the Reynolds number, Re (x-axis) on a log-log scale What is the value of the coefficients of static and sliding friction between two surfaces? Purpose: Included, labeled and organized all parts of the lab report. In this experiment, the frictional force Were your results as expected. Explain.

Friction Force Lab Abstract The purpose of this lab is to help better understand what friction is and how it affects an object’s movement close to the surface of the earth. In our experiment, a box with leather padding on the bottom is pulled by a hanging weight over a ledge. The mass of the hanging weight is used to find the
In this experiment, I learned that static friction has more force than I thought it did. CE 336 lab 5 report friction in pipes.
Your report should include the following: Table(s) of raw data; Table(s) of results; Graph(s) On one graph, plot the experimental and theoretical values of the friction factor, f (y-axis) against the Reynolds number, Re (x-axis) on a log-log scale
In our experiment we will first determine the coefficients of static and kinetic friction between two wood surfaces (a wood block and a wood plank). Diagram 2 illustrates the set-up we will use. The block ( M 1 ) is placed on a horizontal plank and is connected by a string to a weight ( M 2 ), which is hung vertically by means of a pulley. friction oluseye dare gamoi paisley objective: to determine the coefficient of Week 6 - Friction - lab report In this experiment a known force was applied to. formal lab report on the force of friction Force of Friction Lab Report Cite data from the experiment and explain how it supports the relationship.
