Chapter Four 4. Practices in Electricity Generation from Hydropower Hydropower electricity is the product of transforming potential energy stored in water in an elevated reservoir into the kinetic energy of the running water, then mechanical energy in a rotating turbine, and finally electrical energy in an alternator or generator. Hydropower is a mature renewable power generation technology that offers two desirable characteristics in modern electricity systems: first, built-in storage that…

Three: Energy Our universe is made up of matter and energy. Matter is made up of anything that has mass and takes up space where energy allows the ability to do work or have the ability to move or elicit change in matter. In other words, energy is a property of objects which can be transferred to other independent objects or be converted into different forms. It is described as “a system to perform work.” We have two different types of energy; kinetic and potential energy. Kinetic energy is the…

If you are currently in the process of replacing your roof, you should replace your gutters as well. Here are the top three most popular types of gutters that you can have installed on your home. Seamless Gutter Systems Seamless gutter systems are one of the most popular gutter systems installed on homes today.As the name suggests, these types of gutters do not have any seams along them that you have to worry about bursting opening, leaking and needed repaired. Seamless gutters are created by…

It is acknowledged nationwide that everyday things rely on energy. Who would know what a few years without energy would do to the U.S. However, there is a more efficient way of constructing energy such as, sun, wind, and solar. Non-renewable resources should not be used. Non-renewable sources cause effects on human health as in heart disease, lung cancer, and both chronic and acute respiratory diseases, including asthma. In addition, environmental hazards as in including air and water pollution,…

up the universe. Externally, it forms the air and gases in the atmosphere. Internally, Qi is regarded as the energy stored in human body. The concept of Qi can be traced back to the Ancient Chinese Philosophy, in which people held the belief that Qi is the fundamental life force of everything; it forms all matters in the universe and ranges from external environment to the internal energy stored inside the body. Changing of the environment suggests that there are movements and interactions of…

need to ret because of lack of energy or strength occurs. Either of these conditions are simply symptoms. Neither are diseases and both are easily cured and adapted. There are two sites of muscle fatigue. These two sites include the following: central fatigue and peripheral fatigue. There are five factors that affect muscle fatigue and performance. These five factors include the following: diet, central nervous system function, strength and skill, environment, and energy production (anaerobic…

Topic B: Engineering Practice in Oil and Gas Principle 1.0 Introduction to the topic 1.1 Definition of the topic Oil and gas is an important raw material in this era. We are consuming and using hundreds of things that made up from this raw material in our daily life. The oil and gas industry is normally divided into 3 main sectors. There are upstream, midstream and downstream sectors. The upstream sector in charged of exploration and production processes, midstream sector responsible for…

it is not fair to compare the two systems based purely on the magnitude of its COP as the work required in a VA refrigerator is produced by heat, it is much cheaper than the work required in VC refrigerator which require electrical or mechanical energy. Environmental issue Conventional VC refrigerant such as CFC or HCFC can deplete the ozone layer and is already phased out based on the Montreal Protocol. Modern VC refrigerant like HFC - also known as f-gases (fluorinated greenhouse gases) - has…

with the environment (Akin, 2011; Kemp & Krockenberger, 2002;). In Biomimicry, through studying thermoregulation, human beings can apply nature’s techniques to architecture when designing buildings. Present temperature systems are using a lot of energy, especially to control heat and cooling loads. (Carpi 2010). Thermoregulatory mechanisms include passive thermoregulation and active thermoregulation; by studying butterflies and birds more effective climate systems can be developed, leaving a…

characteristics are not equal to the reverse characteristics (i.e. S12 ≠ S21). So, same antenna can be used for Transmission and Reception of Electromagnetic Waves. Antenna is a passive device, it does not amplify the signals, and it only directs the signal energy in a particular direction in reference with isotropic antenna. Antenna Beam width is the angular width measured at the half power points of the main lobe. Large gain of antenna means narrow beam width. Polarization of EM fields…
