Objective: To reproduce the classical experiments conducted by Professor Osborne Reynolds concerning fluid flow condition. 2. Theory: Reynolds number‚ Re is the internationally recognized criterion denoting fluid flow condition. “ Re = 4Q/ πvd ” Osborn Reynolds determined that values of Re could be assigned to define the transition from laminar to turbulent flow. 3.

interstitial fluid‚ and intracellular fluid are identical‚ but the quantity of each substance varies among the compartments. The most striking differences are the low protein content in interstitial fluid compared with intracellular fluid and plasma and the fact that sodium and chloride ions are largely extracellular‚ whereas most of the potassium ions (approximately 90%) are intracellular. This unequal distribution of ions results in a voltage difference across cell membranes. Extracellular fluid can be

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Cash Flows Aleshia Wisch ACC206: Principles of Accounting II Prof. Eric Sumners August 11‚ 2014 ACC 206 Week Assignment 1. Critical Thinking Question: Answer the following questions: Why are noncash transactions‚ such as the exchange of common stock for a building for example‚ included on a statement of cash flows? How are these noncash transactions disclosed? It is important for a company to show what assets they have on hand that can convert to cash. Non cash transactions are disclosed

the functioning of the Circular Flow of Income. The Circular Flow of Income is a model that indicates how money moves throughout an economy. This model was mainly in use up to the Second World War and is a model developed by classical (monetarist) economists. Many models have been developed based on The Circular Flow of Income. The Circular Flow of Income consists of two parts‚ the inner circular flow and injections and withdrawals. In the inner circular flow there are two basic economic institutions

Chapter 5: Flow Rate and Capacity Analysis 5.1 Objective Chapter 3 introduced the three basic building blocks of process flow namely the (average) flow time‚ (average) flow rate and (average) inventory. It is followed by a sequence of three chapters‚ 4‚ 5 and 6‚ which examine each one of these measures individually. Chapter 5 is concerned with flow rate analysis and issues of capacity. The major managerial concept discussed in the in the chapter is that of the bottleneck. We use the notion
