Try these first

1. 1.

   What is the formula for calculating head loss due to sudden enlargement?

   Hint

   Remember the role of the loss coefficient.

2. 2.

   What is the default value of K_entrance if unspecified?

   Hint

   This is a common value used in calculations.

3. 3.

   What is the primary factor affecting head loss in a pipe network?

   • Friction
   • Temperature
   • Pressure

   Hint

   Think about the physical interactions between fluid and pipe walls.

4. 4.

   True or False: All energy is lost during sudden expansions when K_L approaches 1.

   • True
   • False

   Hint

   Reflect on the loss coefficients in sudden expansions.

5. 5.

   Calculate the total head loss in a pipeline that has a major loss of 4m and encounters 3 fittings each causing a minor loss of 0.5m each. What is the total head loss?

   Hint

   Sum major and minor losses to find the total.

6. 6.

   For a conical diffuser with V1 = 5 m/s and V2 = 2 m/s, calculate head loss if KL is known to be 0.8. What is h?

   Hint

   Note the velocities change in calculation for dynamic flow.
