[SOLVED] Earth Science

Assignment 51. (15 points) A wind power generation system produces an average of 1 MW power over half of each 24-hour period and zero power over the other half. If the power consumption is uniform over time and it is planned to use all of the produced power over each 24-hour period, how much battery power storage is needed?Energy storage is in lectures Ch. 6, and energy balance laws in Ch. 2.2. (20 points) To obtain a generated solar heat temperature of 200°C, compare the efficiencies of the two below-described types of solar collectors operating in an environment where the solar radiation flux Iw = 500 W/m2, and its temperature is 15°C.Collector type 1: non-concentrating vacuum-insulated,Collector type2: concentrating with a concentration ratio of 80, with a vacuum-insulated receiver.Both collectors have an overall heat loss coefficient to the ambient UL = 1.5 W/(m2 °C), their absorbers are flat, the window area of each is equal to its absorber area, FR = 0.8, the absorber absorptance ? = 0.95, and the glass window overall transmittance ? = 0.9. Assume that the sun beam is always perpendicular to the absorber/receiver.Explain the results.Sources of information are in Canvas chapter 8 in the course notes (which also contains solar collectors’ calculation examples), but also in the reference books related to this chapter.

[SOLVED] Climate Crisis

There are 2 parts of this assigment:All the readings i will upload, all the videos I will post the link abovePart 1; With specific references to the material, ANSWER BOTH of the below questions. (2 pages)1) What is Gerth’s argument in the video and/or his chapter AND what are the implications for our understanding of the climate crisis?2) How does the Hero (the interview conducted by Sang Ye) prove or disprove the analysis of David Harvey? Again, you must make specific references to the assigned materials.Part 2: Key words (find 3 Key words in the materials I upload and answer following question) (1page)1) Why those three Keywords?2) How do you define those terms?3) How do they help us understand the topics and history covered that week and in the course to date?Much like learning a new language, as your command of Keywords deepens and grows, so does your ability to address the BQs of this course. How do they help us understand the topics and history covered this week and, perhaps, relate to the rest of the course up until now?
