Question:

Smoke Detectors & Ceiling Fans?

I run my ceiling fans all year round (reduces heating/cooling bills by about 15%), but I'm not certain as to the best location of my smoke detectors. At the moment, I have one detector on a wall of each of the rooms, placed 4 to 5 from the ceiling. Is this good enough for small 12' x 14' rooms, or should they be in a different location? OR Are the fans rendering the detectors useless since the rooms are small? (circulating the air in such a way as to prevent proper smoke detection) Thanks

Answer:

the volume of all the water on earth is: 1,360,000,000 km3 1.36*10^9 km3 for a sense of scale the volume of the sun: 1.412×10^27 m3, or 1.412*10^18 km3. the heat capacity of water, times all the water on earth (assuming that when it goes into space, it becomes frozen, and chilled to absolute 0) and accounting for the solid to liquid, liquid to vapor phase changes) while not accounting for any kinetic energy (which is a big assumption), the entire mass of water on earth would take roughly 18.7 * 10^25 kJ of energy to raise to the temperature of the sun, 5778 K. Assuming that no energy is imparted to the water until it reaches the sun (trying to avoid differential equations here) it would take the entire output of the sun 2.355 seconds to emit that much heat. At which point, i can only assume that the water would be broken down into its molecular components and used as fuel. So the sun would briefly dim, flicker, and then produce more energy than before. Also what did you mean by attack?
