Given the following design data for a pressure vessel: Design Pressure, \( P=8.9 \) bar Design Stress, \( \mathrm{S}=123 \mathrm{~N} / \mathrm{mm}^{2} \) Joint Efficiency factor of spot-examined joints of shell and hemispherical head to shell \( =0.85 \) Joint Efficiency factor of seamless heads \( =1.0 \) Internal Diameter \( =2.0 \mathrm{~m} \) Corrosion Allowance \( =3 \mathrm{~mm} \) \( t= \) required wall thickness, mm \( r_{k}=0.152 m \) \( \alpha \) (one half apex angle) \( =30^{\circ} \) Answer the following questions: What is the required thickness of the vessel bhell (t)?
