Q1. How can we design a system for vessel in convection and radiation conditions?
Ans. 
Design a system with insulation to minimize heat transfer in vessel under convection and radiation conditions.
• Use insulation materials with low thermal conductivity to reduce heat transfer

• Incorporate reflective surfaces to minimize radiation heat transfer

• Optimize the design to minimize surface area exposed to convection and radiation

• Consider using double-walled vessels with a vacuum between walls for better insulation

Q2. Explain the strength of materials failure theories and S-N curves
Ans. 
Strength of materials failure theories and S-N curves are used to predict the failure of materials under different loading conditions.
• Strength of materials failure theories, such as the maximum normal stress theory and the maximum shear stress theory, help engineers predict when a material will fail under different loading conditions.

• S-N curves, also known as Wohler curves, show the relationship between stress amplitud...read more
