Challenge Problems
Push your limits with challenges.
Question 1
A fluid flows through a horizontal pipe that narrows at one point. If the pressure at the wide section is 300 kPa and at the narrow section is 250 kPa, determine the velocity at the narrow section if the diameter decreases by half.
💡 Hint: Ensure you relate the areas and velocities correctly.
Question 2
In a water tank, the height of water is 10 meters and is discharged through a small nozzle. If the discharge coefficient is 0.8, calculate the theoretical velocity of the water exiting the nozzle.
💡 Hint: Make sure to substitute 'g' as 9.81 m/s².
