Challenge Problems
Push your limits with advanced challenges
You have a triangular gate submerged at a 45-degree angle at a depth of 3m in water. Determine the required force to maintain its equilibrium against the water pressure.
💡 Hint: Consider how pressure acts differently at various points along the gate.
An inclined manometer shows fluid heights of 150mm of oil (specific gravity 0.8) and 100mm of water. What is the pressure at the gas pipeline connection?
💡 Hint: How do the heights relate to pressures based on specific gravities?
