Reynolds Experiment Essay

2331 words - 10 pages It was in 1883 when Osborne Reynolds, a famous scientist and engineer tried to experiment on the relationship between the stability of fluid motion and the transition to turbulence. His final apparatus consisted of a glass-sided tank, 6 feet long, 18 inches deep and 18 inches wide. Inside it was a glass tube with `a trumpet mouth of varnished wood, great care being taken to make the surface of the wood continuous with that of the glass'. On the right-hand side, the tube was connected to an iron pipe equipped with a valve which could be controlled by means of a long lever. On the left-hand side is the device for introducing a streak of dye into the trumpet, while a float and dial indicated VIEW DOCUMENT

Conservation Of Mass

5535 words - 23 pages Untitled Mass conservation AIM The aim of this experiment is to show that mass is conserved during a chemical reaction. The Law of Conservation of Mass, established in 1789 by French Chemist Antoine Lavoisier, states that mass is neither created nor destroyed in any ordinary chemical reaction. Or more simply, the mass of products by a chemical reaction is always equal to the mass of the reactants. (E, Durnford 1999) The reaction between potassium iodide and lead (II) nitrate under room temperature and atmospheric pressure results with a yellow precipitate. This reaction can be expressed by the equation: 2KI(aq) + Pb(NO3)2(aq) PbI2(s) + 2KNO3(aq) HYPOTHESIS VIEW DOCUMENT

reformation of copper through the copper cycle - texas a&m university; Chem lab 111 - essay

1073 words - 5 pages Reformation of Copper Through the Copper Cycle Authors: Lauren Yarborough* and Alex Farish; Chemistry 112 Section 505. Introduction: Copper is a very important element due to both its chemical and physical properties but has its down sides when it comes to being earth-friendly. Since copper isn’t biodegradable, it just accumulates over time. In this experiment, both my lab partner and I looked at the chemical reactions of copper as it underwent the copper cycle. Materials and Methods: In the first part of this experiment, we obtained 0.2497 grams of copper turnings and placed it into a 50mL beaker. We then obtained 5mL of 6 M HNO3 and placed it into the beaker with a magnetic stir bar to VIEW DOCUMENT

Heat Transfer from Extended Surfaces - Thermodynamics/Heat Transfer Lab - Lab Assignment

939 words - 4 pages Heat Transfer from Extended Surfaces (EDITED) May 10, 2019 Prepared by: Nabeel Abrar Katherine Ramirez Gamma Industries, Inc. Executive Summary How does heat flow in one dimension? This particular apparatus investigated the transient and steady-state temperatures along an alloy rod. In the experiment, a rod was heated at one end over the time span of an hour. Progressively, the temperature down the length of the rod increased, this was monitored by thermocouples. The apparatus’ alloy rod consisted of several embedded thermocouples which read the temperatures at 5 cm increments along the rod length. At the very beginning of the experiment, the temperature of the rod is uniform and at room VIEW DOCUMENT

871 words - 4 pages Samuel Brown & Himesh Premalal Monday April 23rd, 2018 EXPERIMENT 10 Chemical Equilibrium: Reversible Reactions Introduction: The objective of the experiment is to study the effect of stress on the position of equilibrium. This lab focused on the concept of equilibrium and how it can be shifted either to the left or to the right by adding or removing parts of the equation. Chemical equilibrium can be understood as when the forward reaction is equal to the reverse reaction. The goal of the experiment was to see this equilibrium by observing the color change and determining what color changes mean in terms of the reaction and equilibrium VIEW DOCUMENT
