Challenge Problems
Push your limits with challenges.
Question 1
A pipe carrying water has a diameter of 10 cm at point A and 5 cm at point B. If the pressure at point A is 200 kPa and the height difference between points A and B is 2 m, calculate the pressure at point B.
💡 Hint: Use the equation: P1 + 0.5ρv1² + ρgh1 = P2 + 0.5ρv2² + ρgh2.
Question 2
A water tank is open to the atmosphere and has a hole at the bottom. If the hole has a diameter of 2 cm, calculate the speed of efflux using Torricelli's law.
💡 Hint: Consider the height of the water column responsible for this speed.
