Primary energy

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).…

The things that need to be considered are pattern, color and thickness. The filling is probably the most important factor that needs to be considered. The warmth of the duvet is considered by the filling it has. There are four primary types of the fillings of the duvets. They are as following; Wool duvet: Wool is comfortable and extremely comfortable and it is perfect for the winter weather. The wool can trap the body heat and it also has cooling properties in the warmer months…

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…

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…

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…

faster rate of oxidation at the anode. This means a greater number of moles of product. A higher voltage applied to the cell means that the cathode will have enough current to bring about reduction and the same goes for anode, it will have enough energy to bring about oxidation. Higher voltage enables the electrolytic cell to oxidize or reduce difficult compounds. And this can change what products will form in an experiment. Both Voltage and current will determine what will form in a cell.…

additive prepared with different percentages(0,15,25,35 and 45) wt.% and different thickness. The experimental results showed that the D.C electrical conductivity increased with increasing the alumina concentrations and temperature. Also the activation energy change with increasing of additional alumina. The dielectric constant, dielectric loss, A.C electrical conductivity are changed with change the concentration of the filler and frequency of applied electrical field. Keywords: Composites,…

Dipole-dipole array has wide using in resistivity/I.P. surveys because of the low E.M. coupling between the current and potential circuits. The arrangement of the electrodes is shown in Figure( )., Electrodes c1 and c2 are separated by a distance (a), and electrodes p1 and p2 are separated by a distance (b). the distance between the potential electrodes pair c1-c2 is the same as the distance between the potential electrodes pair P1-P2 and the distance between the centers of the respective…
