Question 1.
Define hydraulic gradient line.
Show hintHide hint
Think about how pressure varies in a fluid flow.
Question 2.
What are major losses?
Show hintHide hint
Consider what happens to energy in a pipe due to resistance.
3Question 3.
What is the primary contributor to major losses in a fluid system?
- Friction
- Turbulence
- Fittings
Show hintHide hint
Consider what happens on the pipe surface.
4Question 4.
True or False: Minor losses refer only to friction.
- True
- False
Show hintHide hint
What other components contribute to energy loss?
Question 5.
In a system of three connected reservoirs, with known heights, calculate the required flow discharge when considering both major and minor losses. Make assumptions as necessary.
Show hintHide hint
What equations relate discharge to head loss and flow paths?
Question 6.
Given a horizontal pipe system with specified dimensions and friction coefficients, derive the relationship between flow velocity in two parallel pipes. Use known flow rates to solve for unknowns.
Show hintHide hint
How do variations in pipe diameters affect flow rates?
