Refer the Part-1 of this thin wall pressure vessel design calculation example tutorial series to understand the problem statement. I will use the basic geometry formulas here rather than ASME section viii division 1.

**Pressure Vessel Sizing Calculation**

*Input data (refer problem statement):*

*Type=Thin walled*

*Volume = 30 cubic meter*

*Pressure= 75 Pa*

*Temperature = 90 Degree C*

* Solution:*

*Criteria for Thin wall pressure vessel: r/t>=10*

*We will be using r/t = 225 *

*Let’s assume Thickness (t) =6 mm *

*So, Radius (r) = 1350 mm *

*Volume=30 cubic meter = pi*r^2*h + 4/3*pi*r^3 *

*So, Straight height (h) = 3439.668 mm (we will use 3440 mm hence forth) *

This straight height will be used in the subsequent parts of this thin walled pressure vessel design calculation tutorial series as input for the ASME section eight division one equations.
