When a fluid isn’t moving, the main thing to understand is .
: In the Kingdom of Flow, nothing is ever lost. If 10 gallons of water enter a pipe, 10 gallons must come out the other side (unless it’s being stored somewhere). The Viscosity Veil
Two regimes:
The amount of fluid entering a pipe must equal the amount leaving it.
This explains why planes fly and why a shower curtain might suck inward when the water is running. Basically, as the speed of a moving fluid increases, its pressure decreases. Pascal’s Law: fluid mechanics for dummies pdf
This is the study of fluids in motion. This is where things get wild.
A shower curtain getting sucked inward when the water turns on. When a fluid isn’t moving, the main thing to understand is
). Because fluids have weight, they exert pressure on everything they touch.
Fluid particles move in smooth, parallel layers. Think of smooth, glassy water flowing slowly out of a kitchen faucet. Resistance and friction are low. The Viscosity Veil Two regimes: The amount of
Fluids move in one of two ways: smooth and predictable, or chaotic and wild.
