    39. The Viscosity of Liquids After studying the present lecture, you will be able to Define viscosity and viscosity coefficient Outline the method to measure viscosity using Ostwald viscometer Determine the average molecular weight of a polymer Determine the surface concentration of 1-butanol in aqueous solution Measure the distribution coefficient of a solute betweenn two solvents 39.1 Introduction Viscosity, one of the transport properties, arises because of intermolecular attractive and

  • Viscosity Lab Essay

    721 Words  | 3 Pages

    Viscosity Science Lab Purpose: To determine of changing the viscosity will affect the time it takes for a marble to flow through a liquid. Hypothesis: If a marble is dropped into dish soap and corn syrup, than I predict that the marble in the dish soap will travel faster than the marble in the corn syrup because I know that the viscosity of the corn syrup is thicker than then the viscosity of the dish soap. Also, the particles in the corn syrup are more compact than those in the dish soap

  • Effect Of Temperature On Viscosity

    1709 Words  | 7 Pages

    International Baccalaureate Diploma Program Physics HL Individual Investigation NAME: Barbara Daniels TITLE: The effect of temperature on terminal velocity a falling sphere in liquids of different viscosities Research question: how does the terminal velocity and viscosity of a liquid change as a result of the change in temperature? Personal engagement: People, who have trouble swallowing solids, must often drink thick ones to satisfy their hunger. In traditional markets, most

  • What Liquids Does Viscosity Affect The Most?

    1524 Words  | 7 Pages

    What liquids does viscosity affect the most? I’m going to find out. I’ve always been interested in cooking and how different liquids affect each other and how they react to different things. What liquids are the most viscous and what category do these liquids tend to fall into (cooking, cleaning, etc.)? Viscosity is not normally of knowledge, so what is it? Viscosity shows how much resistance that a liquid has to flow. When liquids have been acted upon by another force, more stresses appear

  • Marble Racing to Find a Liqid's Viscosity

    1612 Words  | 7 Pages

    Your Marbles to Discover a Liquid's Viscosity Which Liquid Has the Highest Viscosity? In this project we will determine the viscosities of 5 separate liquids. The liquids we will test are corn syrup, honey, vegetable oil, milk, and water. We will find their viscosities by dropping a marble into each of these liquids and measuring the time it takes for it to reach the bottom. Before we conduct the experiment, we must first understand what viscosity is. “Viscosity is the quantity that describes a

  • Binder viscosity was altered by changing temperature. The initial dispersion of the binder in the

    Binder viscosity was altered by changing temperature. The initial dispersion of the binder in the powder depends upon viscosity and shear rate applied. (Schaefer, 1996) Binder viscosity also controls the consolidation rate and hence subsequent growth via coalescence. (Ennis, et al., 1991). Results from Rough et al (2005) showed that increased temperature (lower viscosity), the regimes are reached faster because the binder is able to distribute more effectively in the mixture at a given shear rate

  • Effects of Citric Acid on the Viscoelasticity of Cornstarch Pastes

    4045 Words  | 17 Pages

    citric acid on the rheological properties of cornstarch pastes were studied by steady shear and dynamic oscillatory viscoelasticity, intrinsic viscosity measurements and microscopic observation. The pH of cornstarch dispersion was adjusted between 6.0 and 3.0. The viscosity of the pastes was increased by lowering the pH (between 5.5 and 3.6), while the viscosity of samples with pH below 3.5 decreased further than that of the control (pH ) 6.3). Citric

  • Biofuels

    CRUDE OIL CRISIS SAVIOUR .. By focusing our attention from digging for more fossil fuel resources, if we focus it on producing vegetable oil using the land resources, we will greatly reduce the demand for petroleum products. .. Our engine is extremely VERSATILE, being able to run on diesel, bio-diesels, vegetable oils with very little change in power and efficiency. This will diversify the kind of fuels that can run a diesel engine and reduce the dependence on fossil fuels. • ECO-FRIENDLY

  • Transition From Transitional Lava Types

    1447 Words  | 6 Pages

    Transition From Pahoehoe to A’a In its most general sense, as the flow advances away from the vent, core temperature decreases leading to an increase in viscosity and ultimately marks a transition from pahoehoe to a’a. This point of transition is most often referred to as the “transition threshold” (Peterson & Tilling, 1980). Lava which continues to deform even after it has become highly viscous, may reach this threshold and subsequently changes to a’a. There are many factors which govern this change
