We also have attic and wall insulation where there is a difference between the indoor and outdoor temperate‚ the more energy this will take to maintain a temperature of comfort in our homes. By adding insulation between the indoors and the outdoors we are reducing the energy demand. This of course depends on where you live‚ because the savings from insulating your walls

Transformer Introduction The transformer is one of the simplest of electrical devices. Its basic design‚ materials‚ and principles have changed little over the last one hundred years‚ yet transformer designs and materials continue to be improved. Transformers are essential in high voltage power transmission providing an economical means of transmitting power over large distances. The simplicity‚ reliability‚ and economy of conversion of voltages by transformers was the principal factor in the

Theory Project 1 Natural and Manufactured fibres by- Ama Bona Owusu 12MC What are natural fibers? Natural fibers are any hair like raw material that can be directly accessible from an animal‚ vegetable‚ or mineral source (plants) and an be changed into non-woven fabrics such as felt or paper or‚a woven cloth when it has been span into yarns. When natural fibers can be discussed further and can be refereed to as agglomeration of cells in which the diameter is negligible in

Biochemistry Task 5 Shannon Alford Lipid Storage Molecule Conversion to ATP Lipids (also known as fats) are nonpolar‚ insoluble molecules gained within the body trough digestion of food. Triglycerides‚ a type of lipid that serve as storage units for energy have 3 fatty acid chain tails made up of carboxylic acid and a fatty carbon chain attached to a glycerol backbone. These molecules can be saturated or unsaturated contingent on the bond types and hydrogen number in the molecule. Anytime a fatty

In addition to protecting rice during the growing season‚ rice hulls can be put to use as building material‚ fertilizer‚ insulation material‚ or fuel. Production Rice hulls are the coating for the seeds‚ or grains‚ of the rice plant. To protect the seed during the growing season‚ the hull forms from hard materials‚ including opaline silica and lignin. The hull is mostly

CCCH9008 Noise Pollution and Control in HK Two important characteristics of sound or noise Frequency of Sound Sound is the quickly varying pressure wave travelling through a medium. When sound travels through air‚ the atmospheric pressure varies periodically. The number of pressure variations per second is called the frequency of sound‚ and is measured in Hertz (Hz) - cycles per second. Loudness A loud noise usually has a larger pressure variation and a weak one has smaller pressure variation

Some environmental benefits of roof gardens include the following: * Thermal insulation (warms in winter and cools in summer) * Noise insulation * Wildlife habitats * Rainwater detention * Reduced air pollution (plants help trap particulates and gaseous emissions) One of the main advantages of a roof garden in an urban area is the alleviation of

This consists of three sections. • visual inspection • earth continuity test • insulation test The testing for this should be done regularly and are usually every 12 months and this is to be done by a trained professional. Their duties of the visual inspections are to inspect the cables‚ the plugs the casing and any lose components.
