Introduction An isotope is a variation of an atom that already exists. An isotope is different from an atom because of the number of neutrons in its nucleus. Finding the amount of neutrons in an atom can be calculated by subtracting the atomic number of …

Why company should start saving on electricity Nowadays, electricity is a common utilities used everywhere especially on every company. There is numerous ways to save electricity especially on the company premise. Saving on electricity will give many good factors also beside that some negative factors. …

Density determination by pycnometer is a very precise method. It uses a working liquid with well-known density, such as water. For the purpose of this experiment, distilled water was used. The pycnometer is a glass flask with a close-fitting ground glass stopper with a capillary …

Filtration Filtration may be defined as a process of separation of solids from a fluid by passing the same through a porous medium that retains the solids, but allows the fluid to pass through. ” The suspension to be filtered is known as slurry. The …

Introduction The problem our thesis work will solve is to reduce backlash in induction motor. Backlash is described as a mechanical form of dead band that can lead to error on hole location, if the motion required to machine the holes causes a reversal in …

There are many reasons that we need bridges in every day of our life, from sufficient means to pass over a roadway, waterway, railway, or other structure. You don’t even think about them because it takes no effort to get over them and they are …

Title: Finding the Ratio of Mole of Reactants in a Chemical Reaction Purpose of Lab: To find the coefficients of two chemical reactants that appears in a balanced chemical equation using the continuous variations method. Pre Lab Questions: 2AgNO3(aq) + K2CrO4(aq) > 2KNO3(aq) + Ag2CrO4(s) …

1. INTRODUCTION From civil engineering view, Soil is the medium through which the structural loads are transferred safely and efficiently. Soil should be consistent enough to satisfy the requirements even under inevitable circumstances like earthquake, bomb reactions etc. It is necessary to incorporate the seismic …

What is an ionic bond? Typically an ionic bond occurs between one metal and one non-metal ion. One atom borrows one or more electrons from another atom. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to …

BEAM BENDING The bending of beams is one of the most important types of stress in engineering. Bending is more likely to be a critical stress than other types of stress – like tension, compression etc. In this laboratory, we will be determining the Modulus …

Daniel Bernoulli (Groningen, 8 February 1700 – Basel, 8 March 1782) was aDutch-Swiss mathematician and was one of the many prominent mathematicians in theBernoulli family. He is particularly remembered for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability andstatistics. Bernoulli’s work is still studied …

I chose Stephen Hawking to write about for my case study because I have always found him extremely interesting. As a fellow atheist he has come pretty outstanding scientific theories on how our universe came about, none of which are attributed to some fictitious being. …

Doppler effect The Doppler effect, named after Christian Doppler, is the change in frequency and wavelength of a wave as perceived by an observer moving relative to the source of the waves. For waves that propagate in a wave medium, such as sound waves, the …

Aim To determine the relationship between the length of eureka wire, and resistivity of the wire. Hypothesis: As the length of the wire increases, the resistance of the wire will increase. Background: Some materials have consistent resistance at the same temperature regardless of how much …

Nuclear power stations work in fossil fuel-burning stations, except that a “chain reaction” inside a nuclear reactor makes the heat instead.The reactor uses Uranium rods as fuel, and the heat is generated by nuclear fission: neutrons smash into the nucleus of the uranium atoms, which …

DEFINITION OF HEAT TRANSFER| Heat transfer is energy in transit due to temperature difference . Whenever there exists a temperature difference in a medium or between media, heat transfer must occur. The basic requirement for heat transfer is the presence of temperature difference . There …
