Flow Flow rate tells you how much fluid (some volume) passes in a certain time frame.

𝐹𝑙𝑜𝑤 𝑟𝑎𝑡𝑒 = 𝐴𝑟𝑒𝑎 𝑥 velocity

𝐴! = 20 m

" =^4 𝑚

"

The amount of fluid that passes through one

section of the pipe is equal to the amount of fluid

that passes through the other section!

Types of Flow

Laminar Flow

Turbulent Flow 𝑅𝑒𝑦𝑛𝑜𝑙𝑑

𝑠 𝑛𝑢𝑚𝑏𝑒𝑟 = 𝑙𝜌𝑣 ƞ

The higher the Reynold’s number, the more turbulent the flow. Though the flow gets a little rough even under 100, it isn’t considered turbulent until it is up around 20,000 or greater.

Bernoulli’s equation

" " Requirements for Bernoulli’s

• Non compressing fluids
• Must have a continuous flow

How fast will water spray from this LARGE container if a hole is drilled 20 m below the surface level? 𝑃 0 + 𝜌𝑔ℎ 0 + 1 2 𝜌𝑣

= 𝑃 1 + 𝜌𝑔ℎ 1 + 1 2 𝜌𝑣
