Challenge Problems
Push your limits with advanced challenges
Calculate the pressure at a depth of 50 meters in seawater, given that the density of seawater is approximately 1025 kg/m³. Assume gravitational acceleration is 9.81 m/s².
💡 Hint: Don’t forget to check the units for consistency.
A dam needs to hold back water at a depth of 30 meters. If the density of the water is 1000 kg/m³, how thick should the base of the dam be to withstand the pressure without structural failure, if the maximum stress allowed in the material is 5 MPa?
💡 Hint: Always factor in safety and material properties around pressure; thickness design may involve more calculations.
