Q1. You want to keep the indoor temperature of an office at 25o C. The outdoor temperature is 5o C. The heat transfer through the building’s exterior is 3 x 106 kJ. To achieve the desired indoor temperature, you are exploring three heat pumps operating between the office interior and: (i) the ground at 12o C; (ii) a pond at 10o C; and (iii) the air outside at 5o C. For each case, what is the minimum theoretical net work...

An electric utility is considering a new power plant in northern Arizona. Power from the plant would be sold in the Phoenix area, where it is badly needed. Because the firm has received a permit, the plant would be legal; but it would cause some air pollution. The company could spend an additional $40 million at Year 0 to mitigate the environmental problem, but it would not be required to do so. The plant without mitigation would require an initial...

1. Diazepam, has 3 rings, 8 double bonds, and the formula C16H?ClN2O. How many hydrogens does Diazepam have? (Calculate the answer, don't count) I know that 3 rings = 3 Du and 8 double = 1Du, thus there is 11 Du I'm confused on what to do next, the book has C16H34-H22= C16H12 ----->answer is C16H13ClN2O How do you use the 11Du to calculate the number of Hydrogens?

Background: Carolina HeartCare (CHC) plans to spend $6 million to transform 6 recreational vehicles (rv’s) into health labs. The rv’s will tour the Carolinas offering a $99 heart-health workup to anybody who wants one. The workup consists of a detailed questionnaire and some basic diagnostics (blood pressure, ultrasound of the ankle (yep, ankle), cholesterol test, etc). Using the information from the questionnaire and the diagnostics, a statistical analysis will determine the customer’s risk of a heart “malfunction” in the next...
