STEP 1: Convert Input(s) to Base Unit

Internal Pressure in Vessel: 0.52 Newton per Square Millimeter --> 0.52 Newton per Square Millimeter No Conversion Required
Crown Radius for Jacketed Reaction Vessel: 1401 Millimeter --> 1401 Millimeter No Conversion Required
Stress Intensification Factor: 20 --> No Conversion Required
Allowable Stress for Jacket Material: 120 Newton per Square Millimeter --> 120 Newton per Square Millimeter No Conversion Required
Joint Efficiency for Shell: 0.85 --> No Conversion Required
Corrosion Allowance: 10.5 Millimeter --> 10.5 Millimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_hdished = ((p*R_c*W)/(2*f_j*J))+c --> ((0.52*1401*20)/(2*120*0.85))+10.5

Evaluating ... ...

t_hdished = 81.9235294117647

STEP 3: Convert Result to Output's Unit

0.0819235294117647 Meter -->81.9235294117647 Millimeter (Check conversion here)

FINAL ANSWER

81.9235294117647 ≈ 81.92353 Millimeter <-- Dished Head Thickness

What is Design Thickness?

Design thickness is a term used in structural engineering to refer to the thickness of a structural element (such as a beam, column, or plate) that has been calculated or specified based on the design requirements of the structure. The design thickness is the thickness that has been calculated or specified based on the structural requirements of the beam and the strength and deformability of the soil or foundation on which the beam will be supported. The design thickness of a bottom plate is typically determined by a structural engineer or using structural engineering software, and is used to ensure that the bottom plate is able to safely carry the loads that will be applied to it during the life of the structure.
