ABSTRACT Reynolds number can be defined as a number of varieties of situations where a fluid is in relative with motion to a surface. This experiment is to observe the behavior of the flow of fluid either it is laminar or turbulent by calculating it’s Reynolds number and the characteristic of the flow. Other than that‚ the range for laminar and turbulent flow can be calculated and the theory that Reynolds number is dimensionless can be proven. The pump is opened to let the water flow. The dye

geometric shapes‚ which lead to special numbers. The simplest example of these are square numbers‚ such as 1‚ 4‚ 9‚ 16‚ which can be represented by squares of side 1‚ 2‚ 3‚ and 4. Triangular numbers are defined as “the number of dots in an equilateral triangle uniformly filled with dots”. The sequence of triangular numbers are derived from all natural numbers and zero‚ if the following number is always added to the previous as shown below‚ a triangular number will always be the outcome: 1 = 1

Perfect numbers Mathematicians have been fascinated for millenniums by the properties and patterns of numbers. They have noticed that some numbers are equal to the sum of all of their factors (not including the number itself). Such numbers are called perfect numbers. A perfect number is a whole number‚ an integer greater than zero and is the sum of its proper positive devisors‚ that is‚ the sum of the positive divisors excluding the number itself. Equivalently‚ a perfect number is a number that is

Calculate simple indices 2. Determine simple aggregate price indices 3. Use laspeyre’s and Paashe’s price indices to determine weighted indices. What is an index number? An index number is a statistical measure designed to show/ monitor changes over a period of time in the price‚ quantity

pair (one male‚ one female) every month from the second month on. The puzzle that Fibonacci posed was how many pairs will there be in one year? When attempting to solve this problem‚ a pattern is detected: Figure 1: Recognizing the pattern of the "rabbit problem". If we were to keep going month by month‚ the sequence formed would be 1‚1‚2‚3‚5‚8‚13‚21 and so on. From here we notice that each new term is the sum of the previous two terms. The set of numbers is defined as the Fibonacci sequence

The fastest way from point A to point B is a straight line. Scientifically‚ it is a proven fact. Mathematically‚ it is the shortest distance‚ therefore takes the less time. The travel of a straight line is an absolute model of efficiency at its purest. Frederick Winslow Taylor could not have agreed more. Taylor was a firm believer in using science and raw data to determine the most efficient course of action. Guessing was not allowed. Through research and meticulous analysis‚ only then could

Oxidation Number When elements combine to produce a compound‚ each element is assigned an “apparent” charge. This apparent charge‚ the charge an atom would have if both electrons in each bond were assigned to the more electronegative element‚ may be positive or negative. It is called the oxidation number or state of the element in the compound. Oxidation numbers are very useful in keeping track of what happens to electrons when various elements combine to form compounds. By remembering a few

The scientific method is a method for conducting an objective investigation. The scientific method involves making observations and conducting an experiment to test a hypothesis. The number of steps of the scientific method isn’t standard. Some texts and instructors break up the scientific method into more or fewer steps. Some people start listing steps with the hypothesis‚ but since a hypothesis is based on observations (even if they aren’t formal)‚ the hypothesis usually is considered to be the

admissibility of scientific evidence as laid out in Frye v. United States. The court ruled that in order to be admitted as evidence at trail‚ the questioned procedure technique‚ or principles must be “generally accepted” by a meaningful segment of relevant scientific community. This approach requires the proponent of scientific test to present to the court a collection of experts who can testify that the scientific issue before the court is generally accepted by the relevant members of scientific community
