straight pipe, a fully developed laminar assumption is satisfied under the condition that shape change is negligible. Numerical analysis technique the numerical analysis is performed by combining the governing equations related to the conservation of energy, conservation of mass and conservation of electrical charge to examine fluid distributions, heat transfers, mass transfers and electrochemical reactions. The assumptions used in developing the model are as follow: 1) Ideal gas law was…
is called as apparent power. 1.1.1 Active Power “Power is a measure of energy per unit time. Power therefore gives the rate of energy consumption or production. The units for power are generally watts (W). For example, the watt rating of an appliance gives the rate at which it uses energy. The total amount of energy consumed by this appliance is the wattage multiplied by the amount of time during which it was used, this energy can be expressed in units of watt-hours (or kilowatt-hours).…
When the weather turns chilly, people look for extra layers to get warm. The layer approach is useful for providing extra warmth and make your life comfortable and easy in winter. There is a solution for getting warm if you do not need extra layers. The duvets can help you get warm with just one layer. The duvet is just one layer and it acts like a comforter. The duvets are designed to take the place of several layers. The warmth of the duvet depends upon the filling and construction of the…
Most corrosion is an electrochemical reaction. Anything that affects the speed of the chemical reaction will in turn affect the amount of current flow, which will affect the rate of corrosion. The rate of corrosion is directly proportional to the amount of current in the electrochemical corrosion cell. If the current can be measured accurately, then an exact calculation of the metal loss can be made. 2.2.1 ELECTRICAL EFFECTS ON THE RATE OF CORROSION Any issue that have an effect on the…
observations from reported investigations. 5.1. Task 1. Investigating feasible formation conditions and effects of laser power and B content on ultrafine 3DQCN microstructure. 5.1.1. Research questions generation In the TMCs manufacturing, fabrication energy and reinforcement content are two significant input variables [1,9,11], which are related to laser power and B content in laser deposition. Based on the preliminary results (Figure 6 in §4.5), laser deposition with low level of laser power…
Gases, solids, and liquids are the three states that a substance can exist as. A gas does not maintain shape and volume. Gases expand to fit and fill the container. While a liquid maintains volume, but not shape and fits the shape of the container it is placed in. Solids can maintain both volume and shape. When a gas exerts force on the walls of a container, this is known as its pressure. Pressure varies based on temperature and volume. Many gas laws were used within this experiment, such as…

gravity? What is Newtons law? Does friction have to do with motion or force? Does Newton's law apply to everything that is moving? How is movement and forces apply to the world itself? Do natural disasters involve motion and forces? Does energy have to do with motion and forces? How many types of forces are there? How does the earth create forces? Is an earthquake involve motion inside of the earth? What is air resistant type of force? Does motion happen because of force? …
It implies the scope of energy generation the first energy system can provide. (William D. et al. 2010). Method: Participant is weighed (Kg), heart rate monitor is dampened and applied along…
By utilizing heat transfer from the hot combustion gases we can determine temperature distribution in the nozzle. If the temperature distribution and heat flux which are time dependent are given on the surface of wall we can find internal temperature distribution. This problem can be classified as direct heat problem. However many heat transfer problems which occur in practical take transient measurements at more than one location to find heat flux and temperature distribution on the wall. This…
