Challenge Problems
Push your limits with advanced challenges
A fluid flows through a nozzle that has a cross-sectional area of 0.1m². If the fluid has a velocity of 2 m/s at the inlet, and the height difference is 3m, calculate the exit velocity at the nozzle outlet using Bernoulli's equation.
💡 Hint: Use conservation of energy principles to relate inlet and outlet conditions.
Consider an airfoil placed in a wind tunnel with varying pressure readings. If the pressure at the top surface is lower than at the bottom surface, what effect does this have on lift generation?
💡 Hint: Recall how pressure differences relate to forces in fluid mechanics.
