Policy of Academic Honesty
- Midterm 1
- Midterm 2
Exam re-grade requests must be submitted in written form (submit to Prof or TA) detailing the justification for the re-grade. Re-grades will not be accepted beyond 1 week after return of homework / exam.
Homework (and exams) work must follow specific requirements. We will deduct points for not providing all information given in the standard format.
All homeworks have to be submitted on TED and on paper unless otherwise noted. There is no credit for homeworks handed in only on paper or only online.
Paper homeworks have to be handed in by 1pm on Wednesdays. Late homeworks will not be accepted as it disturbs the lecture / students would work on homeworks during the lecture. No exceptions.
10% of the homeworks are randomly selected each time to be manually graded. All other homeworks will not have any points / reader comments / check marks on them (but we confirm that all answers submitted online have a backup paper homework).
For the final grade your lowest homework score will be dropped.
Regrade policy: Within two weeks from the homework due date, submit an email with subject 'Regrade Homework' on TED and explain the reason for the regrade.
- Homework 0: test homework for automated grading due Wed Jan 8 at 1159pm on TED.ucsd.edu. As an exception for this homework, nothing has to be handed in in class.
- Homework 1 Solution, due Mon 1/13, 1pm on TED.ucsd.edu and in class: Book (M&S, 7th edition - 1.32 (also determine absolute and gage pressure in psi), 1.41, 2.8, 2.27: enter the results on TED and submit complete solution by 1pm in class.
Handout problem, submit on TED only: H1.1 Investigate energy consumption in California, the U.S., Canada, and China. Consider:
Write a short paragraph to summarize your findings. Include summary data tables. Cite at least 2 references (can be websites) and include dates (year) of data.
- total energy consumption and energy consumption per capita
- breakdown by sector (i.e., industrial, transportation, residential, and commercial)
- breakdown by source (i.e., coal, natural gas, nuclear, renewable, etc)
- Homework 2 (due 1pm):
Textbook problems 2.54, 2.61, 2.68, 3.44
- Homework 3 (due Jan 29, 1pm): Textbook problems 3.54, 3.59, 3.102, 3.122, 3.135;
Handout Problem (submit on TED only): H3.1 How much energy reaches the Earth from the Sun? Discuss briefly the energy balance of the Earth, including atmosphere and oceans. Write a short paragraph, making sure to cite any references you use.
H3.2 How would you define the efficiency of (a) a power plant and (b) a refrigerator in terms of Wcycle, Qin and Qout? This will be automatically graded. Enter only the term defining the efficiency (i.e. not 'eta=...') and use no spaces, e.g. 'Wcycle/(Qin+Qout)'?
- Homework 4 (due Feb 5 1pm): 4.34, 4.46
Design Project: due Mar. 7 1pm
- Design Project
- Grading Rubric
- Simple template to convey the general idea and structure of the design project.
- Background information:
Heliostat field design with annual efficiencies from Amsbeck et al. (SolarPACES, 2010). You do not have to use this graph for solving the design problem, but it illustrates how mirror efficiency decreases with radius. The function of eta_i versus radius in part 2b is based on this graph.
Guliano et al. (2010) ANALYSIS OF SOLAR THERMAL POWER PLANTS WITH THERMAL ENERGY STORAGE AND SOLAR-HYBRID OPERATION STRATEGY: This document will help you to solve part 3
