   • hfh_fhf​: Head loss due to friction

   • fff: Friction factor

   • LLL: Pipe length

   • DDD: Pipe diameter

   • vvv: Velocity of fluid

   • ggg: Gravitational acceleration

   2.      Effect of Pipe Diameter and Length:

   2. Study how head loss varies with changes in pipe diameter or length.

   3.      Effect of Flow Rate:

   3. Observe the relationship between flow velocity and friction losses.

   4.      Laminar vs. Turbulent Flow:

   4. Identify flow regimes and understand how the friction factor depends on the Reynolds number.
