Question 1.
What is the minor loss coefficient used to quantify?
Show hintHide hint
Think about what factors cause energy loss in fluid motion.
Question 2.
Define head loss in simple terms.
Show hintHide hint
Consider the components of energy in fluid dynamics.
3Question 3.
What does the minor loss coefficient 'k' indicate in fluid mechanics?
- A. Total head loss
- B. Energy loss due to velocity changes
- C. Pressure increase
Show hintHide hint
Focus on flow changes and energy transitions.
4Question 4.
True or False: Gradual contractions are always preferred over sudden contractions in pipe systems.
- True
- False
Show hintHide hint
Think about efficiency in piping design.
Question 5.
Given a fluid flowing with a velocity of 2 m/s through a pipe with a minor loss coefficient of k=0.05, calculate the head loss assuming a smooth gradual contraction.
Show hintHide hint
Using the gravity constant will help you verify your answer.
Question 6.
If the diameter of a pipe is reduced from 0.5 m to 0.25 m with a head loss of 5 m observed, derive how much energy was lost before and after the reduction.
Show hintHide hint
Consider flow continuity and how the diameter affects the velocity.
