21.2. Second Problem - GATE 2015

Try these first

1. 1.

   What is Major Head Loss?

   Hint

   Think about energy lost over distance.

2. 2.

   Name one factor causing Minor Head Loss.

   Hint

   Consider parts of the system where flow is disrupted.

3. 3.

   What are major losses in a pipeline?

   • Friction losses
   • Valve losses
   • Bend losses

   Hint

   Think about what happens along the length of a pipe.

4. 4.

   True or False: Minor losses are always greater than major losses.

   • True
   • False

   Hint

   Consider the components causing each type of loss.

5. 5.

   For a 1200 m long pipe with a diameter of 0.25 m and a friction factor of 0.02, what is the head loss if the total head loss is given as 15 m?

   Hint

   First, calculate the expected head loss due to friction.

6. 6.

   Analyze the impact on flow rate if the elevation difference between two reservoirs is increased to 50 m, keeping all other conditions constant.

   Hint

   Consider the relationship between height and pressure in Bernoulli's equation.
