CORE DEFINITION

When the flow velocity of a liquid is too high, causing local pressure to drop below the saturated vapor pressure, bubbles are formed. These bubbles, when flowing to a high-pressure region, collapse instantaneously, generating enormous impact forces that can erode metal propellers like bullets.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Beware of the destructive power of idle running. When a person or organization operates too fast while lacking sufficient foundation (pressure), a large number of "bubbles" (impetuosity, foam) are generated. The bursting of these bubbles is not just disappearance but will backfire on the entity itself, causing physical structural damage.

Anchor fast decisions

Local high flow velocity of liquid → pressure drops below saturated vapor pressure → dissolved gas/vapor nucleates to form bubbles; bubbles flow to high-pressure region and collapse instantaneously, producing micro-jets and shock waves, repeatedly eroding material surfaces accompanied by noise and vibration. The essence is a "high-speed low-pressure induced phase change - collapse" cycle.

Rate-Limiting Step

The rate-controlling step, also known as the rate-limiting step or rate-determining step (RDS), is a chemical term used to express the slowest step in a chemical reaction. The importance of identifying the slowest step in a chemical reaction lies in the ability to efficiently improve the overall speed of the reaction, thereby achieving higher yields. A common analogy is a narrow water pipe—no matter how fast the water flows, it cannot change the flow rate. The rate-controlling step is the pipe that affects the overall reaction rate.

Pipeline

A pipeline is a system of pipes for long-distance transportation of a liquid or gas, typically to a market area for consumption. Industry datasets indicate the length of the global trunk/transmission pipeline network is on the order of ~2.19 million km by 2025, with North America accounting for ~44%…
