Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does the discharge coefficient (C_d) correct for in fluid dynamics?

  • Viscosity effects
  • Pressure differences
  • Area of the orifice

💡 Hint: Consider why fluids behave differently when moving through small openings.

Question 2

True or False: Steady flow means the flow conditions change over time.

  • True
  • False

💡 Hint: Reflect on how you perceive water flow in a consistent stream.

Challenge Problems

Push your limits with challenges.

Question 1

A large tank sends water through a free jet orifice of area 0.005 m². If the water level falls from 6 m to 3 m during a specific timeframe, calculate the volume of water discharged, given C_d = 0.75.

💡 Hint: Remember to adjust the height as it changes during the discharge time.

Question 2

A city water system uses pipes with a diameter of 10 cm. If a free jet orifice at the end of the pipe has a discharge coefficient of 0.85, analyze the impact of friction on flow rate at the orifice and calculate the expected discharge assuming full water pressure.

💡 Hint: You can utilize the Darcy-Weisbach equation to estimate friction losses.
