Question 1.
Define sudden enlargement in pipe flow.
Show hintHide hint
Think about what happens to fluid speed as it widens.
Question 2.
What does head loss refer to?
Show hintHide hint
Consider the energy as the fluid moves through the pipe.
3Question 3.
What is the formula for calculating head loss due to sudden enlargement?
- \\( h_L = K_L \\frac{V_2^2}{2g} \\)
- \\( h_L = K_L \\frac{V_1^2}{2g} \\)
- \\( h_L = K_L \\frac{A_1}{A_2} \\)
Show hintHide hint
Think about which section is experiencing the change.
4Question 4.
True or False: K_L always equals 1 for sudden enlargement.
- True
- False
Show hintHide hint
Consider how area affects flow.
Question 5.
A pipeline has an entrance with an area of 0.2 m² and exits to a larger area of 1.0 m². If the flow velocity in the entrance is 8 m/s, calculate the head loss due to sudden enlargement.
Show hintHide hint
Ensure you account for gravity!
Question 6.
Determine the practical applications of gradual enlargement in piping systems, explaining how it minimizes energy loss.
Show hintHide hint
Think of environments where energy efficiency is critical.
