1.5. Calculation of Velocities

Try these first

1. 1.

   What causes major head losses?

   Hint

   Think about resistance during fluid flow.

2. 2.

   What does K represent in minor losses?

   Hint

   Consider its role in calculating losses from bends.

3. 3.

   What are major losses primarily caused by?

   • Friction
   • Bends
   • Valves

   Hint

   Consider the main component causing resistance.

4. 4.

   True or False: Minor losses occur due to friction.

   • True
   • False

   Hint

   Think about the elements in flow that cause resistance.

5. 5.

   You are given a complex piping system with multiple fittings and expansions, where the total head loss is 12 meters and known losses from fittings is 3 meters. Calculate the flow rate in the larger pipe if its diameter is 0.4 meters.

   Hint

   Stay focused on balance between known and unknown parameters.

6. 6.

   A network's flow is distributed through 4 pipes with known diameters. The initial flow rates are distributed non-uniformly. How can the Hardy Cross Method be applied to adjust these rates for equilibrium?

   Hint

   Focus on balancing head losses around the network loop.
