Try these first

1. 1.

   What equation is used to describe pressure distribution in hydraulic engineering?

   Hint

   Think about what principles relate to energy conservation in fluid mechanics.

2. 2.

   Define dynamic pressure.

   Hint

   Consider how the pressure changes when the fluid is in motion.

3. 3.

   What principle does the Bernoulli equation uphold regarding fluid motion?

   • Conservation of temperature
   • Conservation of energy
   • Conservation of mass

   Hint

   Consider which physical law relates to fluid motion.

4. 4.

   True or False: Dynamic pressure is constant at different wave elevations.

   • True
   • False

   Hint

   Reflect on how pressure changes when a fluid is moving.

5. 5.

   Consider a wave system with a wavelength of 10m and amplitude of 2m. Calculate the wave velocity and discuss how this influences group celerity.

   Hint

   Focus on the equations relating wave attributes to velocity.

6. 6.

   In a practical scenario, if the static pressure at a depth of 5m is measured at 50kPa, what would be the dynamic pressure if the wave causes a motion velocity of 2m/s?

   Hint

   Refer to Bernoulli’s fundamentals for equations on pressure.
