A piston-cylinder device initially contains 0.08 m^3 of nitrogen gas at 130
kPa and 170°C. The nitrogen is expanded to a pressure of 80 kPa via
isentropic expansion. Determine the final temperature and the boundary
work done by the system during this process.
A Carnot (ideal) heat pump is to be used to heat a house and maintain it at 22°C
in winter. On a day when the average outdoor temperature remains at about 0°C,
the house is estimated to lose heat at a rate of 65,000 kJ/h. If the heat pump
consumes 6 kW of power while operating, determine:
(a) how long the heat pump ran on that day
(b) the total heating costs, assuming an average price of 11¢/kWh for electricity
(c) the heating cost for the same day if an 85% efficient electric furnace is used
instead of a heat pump.
From the information in the image, I needed to find the orientation of U relative to Q in vector basis q_hat. I transformed the euler angle/axis representation to euler parameters. Then I got its conjugate in order to get the euler parameter in N frame relative to Q. The problem gave the euler angle/axis representation in Q frame relative to N, so I needed to find the conjugate. Then I used the euler parameter rule of successive rotation to find the final euler parameters that describe the orientation of U relative to Q. However that orientation is in n_hat which is the intermediate frame. How do I get the final result in q_hat?

- A proposed method of power generation involves collecting and storing solar energy in large artificial lakes a few meters deep, called solar ponds. Solar energy is absorbed by all parts of the pond, and the water temperature rises everywhere. The top part of the pond, however, loses much of the heat it absorbs to the atmosphere, and as a result, the cool surface water serves as insulation for the bottom part of the pond and helps trap the energy there. Usually, salt is planted at the bottom of the pond to prevent the rise of this hot water to the top. A heat engine that uses an organic fluid, such as alcohol, as the working fluid can be operated between the top and the bottom portions of the pond. If the water temperature is 27°C near the surface and 72°C near the bottom of the pond, determine the maximum thermal efficiency that this power plant can have.
