Question 1

What is the formula to calculate acceleration in fluid flow?

  • A = du/dt
  • A = dV/dt
  • A = dP/dt

💡 Hint: Recall the definition of acceleration in the context of fluid mechanics.

Question 2

True or False: In a steady flow, local acceleration is typically non-zero.

  • True
  • False

💡 Hint: Think about the implications of 'steady' in fluid dynamics.

Challenge Problems

Push your limits with challenges.

Question 1

If a fluid passes through a nozzle, entering at 15 ft/s and exiting at 35 ft/s, compute the average acceleration if the time taken was 2 seconds. How does this relate to the principles of continuity?

💡 Hint: Remember how velocity and area are interconnected in continuous flow systems.

Question 2

Given a reducing diameter nozzle with inlet diameter D1 = 4 inches and outlet diameter D2 = 2 inches, if the fluid enters at a velocity of 20 ft/s, calculate the exit velocity.

💡 Hint: Ensure you remember the area calculation for circular sections.
