AI Thread Summary

Water will flow out of a tank faster through a single large hole compared to multiple small holes of equal total area due to the principles of fluid dynamics. The larger hole allows for less resistance and greater flow rate, while small holes may create turbulence and restrict flow. If the tank bottom has significant thickness, it could affect the flow rate, but the size of the holes remains critical. If holes are too small, they may prevent water from escaping entirely, especially if the water molecules are larger than the holes. Ultimately, the size and number of holes significantly influence the rate of water dispersion from the tank.

In which case would water fall out of the tank faster?
1) If I were to take a tank filled with water and bore a large hole in the bottom of it with some area
2) Riddle the bottom of the tank with small holes that have an area that adds up to the area of the first big hole.

In one scenario let's assume that the material of the bottom of the tank has no thickness. What about if there is some significant thickness? Is it possible that the holes can become small enough (but numerous enough to still sum up to the required area) that no water will escape? Maybe the water molecules could be larger than the holes?

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
