Enter this prompt. "*[[Calculate the pipe diameter for a flow rate of 0.2 m³/s at a velocity of 2 m/s.]]* [[Zero-shot Prompting uses the AI’s baseline training to provide responses without any added guidance or context. This makes it quick but can lead to incomplete or generalized results.]]

To calculate the pipe diameter, we can use the continuity equation:

𝑄
=
𝐴
⋅
𝑣
Q=A⋅v

Where:

𝑄
Q = Volumetric flow rate (

/s)
𝐴
A = Cross-sectional area (
𝑚

m

)
𝑣
v = Velocity (
𝑚
/
𝑠
m/s)

Rearranging for the cross-sectional area:

𝐴

The required pipe diameter is 0.357 meters.

[[The AI applies the basic formula for pipe diameter correctly but doesn't account for specific engineering standards or conditions.]]
