Challenge Problems
Push your limits with advanced challenges
A sealed container holds a fluid at 30°C and is subjected to an external pressure of 200 kPa. The fluid's density is 850 kg/m³. If the maximum depth of the fluid in the container is 20 m, calculate the absolute pressure at the bottom of the container.
💡 Hint: Pay attention to units; you may need to convert pressures into the same units.
In a U-tube manometer, the fluid on the left side is oil with a density of 800 kg/m³ and the right side is water (1,000 kg/m³). The oil height is 0.15 m, and water height is 0.10 m. Determine the pressure difference between the two sides.
💡 Hint: What weight of fluid creates pressure? Relate heights to density.
