What is the relation between exit velocity and entrance velocity in a nozzle?
💡 Hint: Think of common nozzle design examples.
True or False: Convective acceleration is caused by changes in velocity due to movement through a velocity gradient.
💡 Hint: Consider how fluid parcels behave in movement.

Challenge Problems
Push your limits with advanced challenges
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.
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.
