Question 1

Easy

What is the formula for calculating acceleration in the x-direction in a nozzle?

💡 Hint: Think about how velocity changes involve both time and space.

Question 2

Easy

If the entrance velocity is 10 ft/s, what is the exit velocity if it increases threefold?

💡 Hint: Multiply the entrance velocity by 3.

Question 1

What is the relation between exit velocity and entrance velocity in a nozzle?

  • Exit = Entrance
  • Exit = 2 * Entrance
  • Exit = 3 * Entrance

💡 Hint: Think of common nozzle design examples.

Question 2

True or False: Convective acceleration is caused by changes in velocity due to movement through a velocity gradient.

  • True
  • False

💡 Hint: Consider how fluid parcels behave in movement.

Challenge Problems

Push your limits with challenges.

Question 1

A nozzle reduces its diameter from 10 cm to 5 cm. If the inlet velocity is 20 m/s, determine the outlet velocity and changes in pressure in the streamline flow.

💡 Hint: Consider both conservation of mass and energy principles.

Question 2

In a conical nozzle, the entrance is 1 m wide, and the exit is 0.25 m. Calculate how speed changes if the entrance velocity is 8 m/s.

💡 Hint: Think about how the cross-sectional area influences flow.
