Power Curve Essay Example | Topics and Well Written Essays - 500 words

Power Curve - Essay Example It can be modeled in a similar manner to that of the pressure that develops from molecular viscosity. That means that there is eddy viscosity that acts as super viscosity and can provide turbulent stress when multiplied by the mean gradients. Eddy viscosity is valuable since it provides us with a way to estimate the new terms developed by inserting the Reynolds decomposition through closure of the turbulent flow equations. 4- Solar insolation leads to large eddies especially during the day. The convective turbulence also leads to the development of a mixed boundary layer. The energy shuts down, and the turbulence keeps spinning aloft as the sun goes down. However, the energy is also suppressed down towards the ground due to the stably stratified turbulence. Suppression of the vertical motions by the stable flow forces the stable boundary layer to be thinner. 5- The twist in typical wind turbine blades occurs due to the differences in relative velocity wind vector (May 212). There are larger components of wind that are associated with the relative motion that occurs between the blade and the air at large. 6- One of the issues discussed in class was the current bottleneck with transmission lines. The second was the dual challenges that occur when competing with local companies that are invested and maintained by the state. 7- Turbulent energy develops from the large scale motions and gradients in the governing equations. For instance, flow instabilities get transferred to the medium scale motions, which transfer to the smaller scale motions. The smaller scale gradients become large enough and force the viscosity to dissipate turbulent kinetic energy. At the inertial subrange, turbulent kinetic energy passes through this range of scales without much dissipation. 11 – The variability of wind the resource is equal to the variability of wind power. On the other hand, the variability of fuel costs is

Megacities in Asia - Tokyo Assignment Example | Topics and Well Written Essays - 250 words

Megacities in Asia - Tokyo - Assignment Example This meant building high rise buildings to offer office space for increased business. Though this was faced with frequent cases on sunshine rights, the government was able to move the communities out of the city to suburbs by buying the land in central Tokyo (Sorensen 2003, p527). The rapid growing population meant more commutes per day. The government developed subways, overpasses and wide roads across the city to ease transport. As busy as the city is, traffic was a major factor. The solution to this problem was an understanding between the government, developers and the general public on the need to develop the city. Any chance of creating pace in Tokyo is deemed important since there is more demand for offices and residential houses. The model used in Tokyo can be applied in other cities in Asia. This is because sacrifice is inevitable for development. However, this should be done in consultation with stakeholders to avoid conflicts between developers and the public. Asian cities are marred by poor urban planning that lead to chaos in terms of traffic and residential
