If liquid is not compressible, why do we need special hydraulic fluid? Why not just use water?
In: Engineering
I know a colleague who works EXACTLY on that. The short answer : water is weird man. The long answer : when you compress water, the results in the way it moves are really unpredictable. Sometime you get vertices, sometime you get a pressure gradient etc. What is even worse for this is that it’s not completely dependent on the system’s specs, you can test the same water-based system 10 and obtain 10 different results.
According to him, it’s because water is a small enough molecule to be on the verge of atomic and quantum physics, not sure about that tho.
