Introduction The purpose of this lab is to create two material samples through the process of powder metallurgy. After these samples have been manufactured completely through this process then they are evaluated under a microscope. One sample was sintered, and the other one was in its original compacted state for a comparison of how sintering…

Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique, an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution…

Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves are waves of…

Performance Characteristics of Belton Wheel (Impulse Purpose: To investigate typical performance characteristics of an impulse turbine. Apparatus: Ramified Belton Turbine, Ramified Hydraulics Bench and digital tachometer. Sketch a labeled schematic diagram of the apparatus. Theory and Definitions: (Ref. Munson/Young/Schools A Brief Introduction to Fluid Mechanics, 3/e, p. 479) 1. Ideal power and efficiency From 1…

Discussion The process of consolidation is often confused with the process of compaction. Compaction increases the density of an unsaturated soil by reducing the volume of air in the voids. Meanwhile, Consolidation is a time-related process of increasing the density of saturated soil by draining some of the water out of the voids. According to…

The various types of contamination of wastewater require a variety of strategies to remove the contamination Brine treatment Brine treatment involves removing dissolved salt ions from the waste stream. Although similarities to seawater or brackish water desalination exist, industrial brine treatment may contain unique combinations of dissolved ions, such as hardness ions or other metals,…

Windmills are “structures or machines that convert wind into usable energy through the rotation of a wheel made up of adjustable blades. ” They are used for pumping water, grinding grain, and for power. Windmills are usually found on homesteads or on farms. The first windmill was built in the 1st century by Heron of…

Introduction             Electroplating can be defined as the deposition of a metallic coating through the subjection of an object with a negative charge to a solution containing a salt containing positive metal ions. Under the influence of an electric charge, the positive ions are attracted to the negatively charged object where they are reduced hence…

During the first decade of the twentieth century the world-wide demand for ammonia for use in fertilisers (in the form of nitrates) and in the production of explosives for use in mining and warfare could only be satisfied on a large scale from deposits of guano in Chile (2). Though this deposit was of huge…

Challenge To design and build a pop bottle rocket to fly as far as possible. Research Pop bottle rockets are used for the study of aeronautics all over north America. Water rockets are used in schools to help students understand the principles of aeronautics. The Science provides challenges of bottle rocket design and flight, including…
