21.3. Third Example - GATE 2015

Try these first

1. 1.

   What are major losses in a pipeline?

   Hint

   Think about where friction occurs in fluid flow.

2. 2.

   What does the Darcy-Weisbach equation calculate?

   Hint

   Recall the parameters involved in the equation.

3. 3.

   What is a major loss in pipelines?

   • Loss due to fittings
   • Loss due to friction
   • Loss due to elevation

   Hint

   Consider energy lost due to friction.

4. 4.

   True or False: Minor losses are not significant in fluid systems.

   • True
   • False

   Hint

   Think about the impact of bends and valves.

5. 5.

   A 1 km pipe has a diameter of 0.5 m and a friction factor of 0.02. Calculate the flow rate if the head loss is set to 30 m.

   Hint

   Relate head loss to the Darcy-Weisbach equation to find velocity first.

6. 6.

   In a system with two reservoirs separated by a distance of 500 m with various bends and fittings, calculate the total discharge, incorporating all major and minor losses.

   Hint

   Ensure to keep track of all losses including entry and exit losses.
