18.. Introduction to Pipe Systems Design

Try these first

1. 1.

   What is head loss in a pipe system?

   Hint

   Think about the energy that is not making it to the flow.

2. 2.

   Name one factor that influences the friction factor in pipes.

   Hint

   Consider how smooth or rough surfaces affect the flow.

3. 3.

   What principle does Bernoulli's equation illustrate?

   • Conservation of mass
   • Conservation of energy
   • Conservation of momentum

   Hint

   Consider what happens to energy as water flows.

4. 4.

   Head loss is primarily caused by:

   • True
   • False

   Hint

   Think about how fluid speed and flow path affect energy.

5. 5.

   If a water pipeline has a length of 200 meters and a diameter of 0.5 meters, flowing water at 3 m/s with a friction factor of 0.02, calculate the head loss using the Darcy-Weisbach equation.

   Hint

   Break down the equation step-by-step, and ensure you keep track of units.

6. 6.

   How would the introduction of a new roughness factor, changing from a smooth pipe to a textured pipe, affect energy efficiency in a water supply system?

   Hint

   Consider how friction impacts flow rate and energy.
