Scaling laws by degree of knownness
Very widely known
ATM barely any descriptions on the listed pages here. Most is on page: Scaling law.
I advise visiting any of the countless sources on the web for details.
- Twice the surface area of half the volume
- Thousandfold lower mass of tenfold smaller machinery
- Twice the frequency of half sized machinery
Somewhat known
More details here:
- Same absolute speeds for smaller machinery
Usually formulated indirectly by stating that machine frequencies rise linearly with falling size.
This one is basically equivalent: Twice the frequency of half sized machinery
Not a size but a speed scaling law:
- Hundredfold smaller frictionlosses from tenfold slowdown
There might still be dissipation mechanisms that scale differently.

Very poorly known (but very important)
Less relevant but a bit flabbergasting:
