1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs. The process of urine formation and adjustment of blood composition involves three

Questions and Hypothesis: Seed germination‚ plant growth‚ and sprouting of leaves are affected by several factors: supply of nutrients‚ water‚ exposure to sunlight‚ and conditions of surroundings. Due to certain stimuli in the surroundings plant “hormones” cause plants to behave in ways that ensure the most efficient use of resources while preserving the most energy. One stimulus to consider‚ is the exposure of plants to sunlight; when plants are just sprouting and are underground‚ the sti

Acidic vs. Alkaline Introduction: Potential of hydrogen‚ or pH‚ is a scale used to express the acidity or alkalinity of a solution. The scale ranges from 0 to 14‚ below seven represents acidity‚ seven is neutral‚ and more than seven is basic. Acid-base indicators show whether the solution is acidic or alkaline. They do this by reacting with the solution‚ seen as a color change‚ as the concentration of hydrogen (H+) or hydroxide (OH-) ions changes in an aqueous solution. Different indicators

William Piumbroeck Chem 214 Acid-Base Titration‚ Determination of Carbonate and Bicarbonate in a water sample Introduction The purpose of this lab is to determine the concentration of two bases‚ carbonate and bicarbonate‚ by using a potentiometric titration. We can determine the concentration of the bases in the reactions ( H+ +CO3- < ==> HCO3- and H+ + HCO3- < ==> H2CO3-) by the way the pH of the solution changes. The way the pH changes when a strong acid is added can

Introduction In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and
