Challenge Problems
Push your limits with advanced challenges
A cylindrical tank is filled with water providing a gauge pressure of 50 kPa at the bottom. Assuming the tank’s surface area is 2 m², calculate the total force exerted by the water on the bottom surface.
💡 Hint: Recall the relationship between pressure, area, and force.
Consider a control volume around a pipe with both inlet and outlet. If the fluid's velocity changes due to friction, describe how shear stress could be affecting the flow at different pipe sections.
💡 Hint: Reflect on how viscosity plays a role in friction.
