Challenge Problems
Push your limits with advanced challenges
A horizontal pipe has a diameter of 0.5 m at point A and 0.2 m at point B. If the fluid is water at a pressure of 50 kPa at A, find the pressure at point B assuming no height differences.
💡 Hint: Use A1V1 = A2V2 for the velocities and substitute into Bernoulli's equation.
Water flows from a tank through a pipe with a valve. The height of the water tank is 10 m; find the velocity of water at the exit of the valve, assuming atmospheric pressure at the exit.
💡 Hint: Why does the tank height matter for the exit velocity?
