Enter this Prompt to calculate the pipe diameter using the few shot prompting technique: "*Calculate the pipe diameter for a flow rate of 0.1 m³/s at a velocity of 1 m/s.\
D = √(4Q/πv)\
D = √(4 × 0.1 / π × 1)\
D = 0.357 m.*

*Example 2: Calculate the pipe diameter for a flow rate of 0.3 m³/s at a velocity of 3 m/s.\
D = √(4Q/πv)\
D = √(4 × 0.3 / π × 3)\
D = 0.357 m.*

*Now calculate the pipe diameter for a flow rate of 0.2 m³/s at a velocity of 2 m/s."*\

Example 1: Calculate the pipe diameter for a flow rate of 0.1 m³/s at a velocity of 1 m/s.

D = √(4Q/πv)

D = √(4 × 0.1 / π × 1)

D = 0.357 m.

Example 2: Calculate the pipe diameter for a flow rate of 0.3 m³/s at a velocity of 3 m/s.

D = √(4Q/πv)

D = √(4 × 0.3 / π × 3)

D = 0.357 m.

Now calculate the pipe diameter for a flow rate of 0.2 m³/s at a velocity of 2 m/s."
