Question 1.
What is flow rate?
Show hintHide hint
Remember the unit is usually cubic feet per second.
Question 2.
What is the continuity equation?
Show hintHide hint
It connects area and velocity with flow rate.
3Question 3.
What does the continuity equation express?
- A flow rate law
- Conservation of mass in flow
- Relationship of pressure only
Show hintHide hint
Consider mass as fluid moving through a pipe.
4Question 4.
True or False: Bernoulli's equation indicates energy loss in a system.
- True
- False
Show hintHide hint
Remember we talk about efficiencies in real applications.
Question 5.
Given a rectangular channel with a width of 4 feet, a height of 2 feet, and a flow rate of 8 cubic feet per second, calculate the velocity and discuss if it experiences subcritical or supercritical flow.
Show hintHide hint
Evaluate depth with respect to flow profile to assess conditions.
Question 6.
A ramp in a channel accelerates flow from 1 ft/s to 3 ft/s across a height of 0.5 feet. Calculate the energy loss and the significance of such a design.
Show hintHide hint
Consider both potential energy loss due to elevation and kinetic energy gain.
