1.5. Example Problems

Try these first

1. 1.

   Define velocity defect.

   Hint

   Think about how velocity changes in a pipe.

2. 2.

   What are major losses in fluid flow?

   Hint

   Consider the impact of the pipe's surface on flow.

3. 3.

   What is the velocity defect?

   Hint

   Think about how turbulence changes velocity measurements.

4. 4.

   True or False: In pipes arranged in series, the total discharge is different in each pipe.

   Hint

   Consider the behavior of fluids through connected pipes.

5. 5.

   A pipe system has two sections in series with head losses of 10m and 5m. If the total energy available is 20m, calculate the velocity of the fluid if the pipe diameter is 0.2m.

   Hint

   Use this head to find out how much fluid flows through the pipe.

6. 6.

   In a three-reservoir junction, the head at points A, B, and C are 12m, 8m, and 6m respectively. If we know resistance in each pipe, find flow direction considering energy loss.

   Hint

   The total discharge has to account for energy losses at different points.
