Challenge Problems

Push your limits with challenges.

Question 1

A pressure vessel is subjected to 300°C with an internal pressure of 10 MPa. Calculate the thermal stress if E = 200 GPa and α = 18 × 10^-6 /°C. Assume ΔT = 300°C.

💡 Hint: Break down the problem by calculating thermal stress separately first.

Question 2

Evaluate how increasing the internal temperature affects the safety of a pressure vessel designed to hold 15 MPa at 150°C. Discuss the design considerations needed for a rise to 300°C.

💡 Hint: Think about how materials have limits and how increasing temperature affects material properties.
