INTRODUCTION: A high Reynolds number Newtonian liquid jet‚ exiting a two-dimensional channel‚ is examined in this study. Fully developed Poiseuille flow‚ driven by an applied pressure gradient‚ is assumed to prevail upstream of the channel exit. Flow is assumed to be laminar‚ steady and incompressible. A free surface develops as the fluid exits the channel. The resistance of the air on the free surface of the liquid jet can be neglected so that‚ the shear stress at the channel wall disappears and

How to maintenance of liquid assets to ensure frm has adequate cash? Asking the above-referenced question without statistics makes it impossible for anyone to give you a proper answer. Generally speaking‚ you must limit expenses and ensure that some of your assets are in the form of short term assets. The higher your short term assets and the less your short term debt‚ the better your ability to pay the debt (short term liquidity ratio / liquidity ratio help you determine this). There is no

Extraction of metals The History of Metals. Metals have been used by people for many thousands of years. Gold and silver‚ found as native metal‚ were used both as jewellery and as a status symbol - nothing new there. These metals were known in the Stone Age‚ but gold and silver are too soft to be used as tools. The first really useful metal to be discovered was bronze. This began the Bronze Age. Bronze was used extensively for tools and weapons in Asia and Africa from 4‚500 B.C. (6‚500 years

called extraction. Extraction is a systematic process of separating mixtures of compounds‚ taking advantage of the affinity differences of compounds to separate them (Padias 128-37). This technique recognizes the principle that “like dissolves in like‚” that is‚ polar solutes dissolve in polar solvents and non-polar solutes dissolve in non-polar solvents. Through extension of this principle‚ one can use extraction to separate compounds of a mixture. There are three different methods of extraction; solid-liquid

Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental level
