Challenge Problems
Push your limits with challenges.
Question 1
A pressure vessel is subjected to 300Β°C with an internal pressure of 10 MPa. Calculate the thermal stress if E = 200 GPa and Ξ± = 18 Γ 10^-6 /Β°C. Assume ΞT = 300Β°C.
π‘ 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 150Β°C. Discuss the design considerations needed for a rise to 300Β°C.
π‘ Hint: Think about how materials have limits and how increasing temperature affects material properties.
