AI Thread Summary

Flat propellers, when rotating, can exhibit properties similar to a solid circular mass at certain speeds, although they will never fully mimic it. The discussion highlights that the speed required for this effect varies based on the application and design of the propellers. While the primary focus is on the theoretical aspects, it is acknowledged that flat propellers can still produce some propulsion. The conversation emphasizes the complexity of achieving solid mass characteristics with flat designs. Ultimately, the relationship between speed and propeller design remains a nuanced topic in fluid dynamics.

If you had a set of flat propellors (propellors that are not curved and do not

.. propel), at what speed would they need to be rotating for them to take on the properties of a solid circular mass of the material?

P.S. sorry if this is vague

They never really would, but you can simplify depending on the application.
They also actually would cause some propulsion.

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...

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
