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 acid promoted the collapse of starch granules; however

What is crude oil? Crude oil is a naturally occurring liquid found inside certain rocks trapped beneath the Earth’s crust. It is dark and sticky‚ classified as a hydrocarbon‚ or rather mixture of hydrocarbons. We separate them in order to make something useful during a process called fractional distillation. Since it is highly flammable and can be burned to make energy‚ it is used as a major fuel source on our planet. This oil is a fossil fuel‚ what means that there is a limited supply

27.0% and 30.0% whereby the differences are not major and in the acceptable range. There are few factors in affecting the head loss which are flow rate‚ inner diameter of the pipe‚ roughness of the pipe wall‚ corrosion and scale deposits‚ viscosity of the liquid‚ fittings and also straightness of the pipe. There are existence of both human errors‚ parallax errors and environmental effect but there are always error counters to be taken place to increase the accuracy of the results. Introduction

The type of physics that I will be presenting is a branch of Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster’s Medical Dictionary‚ via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics‚ including

Slightly viscous liquid. When stored correctly‚ in sealed containers‚ Helizarin Binder UDT has a shelf life of 12 months. After product has been removed‚ opened drums must be properly resealed‚ because the product tends to form a skin when it is exposed to the air. Properties

polymer-modified (SBS) bitumens. In total‚ an unmodified bitumen‚ five ground tire rubber-modified and three polymer-modified (SBS) bitumens have been studied. Rubber-modified bitumens show improved viscoelastic characteristics and‚ therefore‚ higher viscosity than unmodified binders. Consequently‚ enhanced resistance to permanent deformation or rutting and low-temperature cracking should be expected in ground tire rubber-modified bitumens. In addition‚ rubber-modified bitumen (9 wt.%) shows very similar
