7.26. The conversion of the kinetic energy of wind to electricity may be an attractive altemative to the use of fossil fuels. Typically, wind causes the rotor of a turbine to turn, and a generator converts the rotational kinetic energy ofthe rotor into electricity. Power generated by a wind turbine (Ws) can be estimated from the density of the air (p), wind speed (u), and turbine rotor diameter (D) using the following formula лD? 1 W. ти* х п, where...

i) Compare in short paragraphs the global warming impact of solar energy and fossil fuels. (4 marks) ii) Today nearly all of Oman's electrical energy is generated from natural gas. But by year 2030, Oman targets to produce 30% of its electricity from renewable energy. If it is projected that by year 2030, Oman's total electrical energy need will be 30 x 109 kw-hr, estimate how many tons of global warming CO2 will be produced if Oman's electricity source will...

Problem 2: Pedal Power
Many villages in the developing world lack access to electricity.
One proposed solution is the ‘Free Electric’ bicycle, which is a
stationary bike hooked up to a generator and battery. Pedaling the
bike powers the generator, which creates electricity that is stored
in the battery. The inventor claims that 1 hour on the bike can
produce a whole day of electricity. Let’s put it to the test!
Assume the following: The human body is 25%...

Energy comes in many different forms, but they share a common bond - they are the source of change, the root of the force. Energy moves through our world by force and action, changing from one form to another. Of course the energy is really the same, but it is our human need to classify what we see that creates the separate designations. We artificially separate energy into different categories for our ease of use. For most of these categories...

CODE 102_8 Welding Many welding processes require the application of heat and/or pressure to produce a suitable bond between the two parts being joined. There are a number of conventional and commercially practiced welding processes, which possess limitations in relation to material type and thickness, and in addition, the cost analysis may not allow for a process to be used on a specific application. The selection of suitable welding consumable (electrode or wire) is also an important factor in producing...
