Question 1.
What does the mass flow rate equation consist of?
Show hintHide hint
Relate it to density, area, and velocity.
Question 2.
Define hydrostatic pressure in a fluid.
Show hintHide hint
Think about pressure in terms of depth and weight of fluid.
3Question 3.
What is the equation for wave speed for small amplitude waves?
- c = gy
- c = sqrt(gy)
- c = g/y
Show hintHide hint
Consider wave speed's dependence on depth.
4Question 4.
True or False: The wave speed increases with larger wave amplitudes in small amplitude wave theory.
- True
- False
Show hintHide hint
Reflect on the derived equations.
Question 5.
A solitary wave travels at 3 m/s in a channel 1.5 m deep; determine gravitational acceleration.
Show hintHide hint
Use the derived formula to show your calculations.
Question 6.
