Check the requirements of UG-33(a)(1) using P = 1.67 * External Designpressure for this head.


Required Thickness due to Internal Pressure [tr]:= (P*D*K)/(2*S*E-0.2*P) Appendix 1-4(c)= (1.762*955.9999*1.000)/(2*1406.14*1.00-0.2*1.762)= 0.5990 + 3.0000 = 3.5990 mm

Max. Allowable Working Pressure at given Thickness, corroded [MAWP]:= ((2*S*E*t)/(K*D+0.2*t))/1.67 per Appendix 1-4 (c)= ((2*1406.14*1.00*7.0000)/(1.000*955.9999+0.2*7.0000))/1.67= 12.313 kgf/cm

The Natural Frequencies for the vessel have been computed iterativelyby solving a system of matrices. These matrices describe the massand the stiffness of the vessel. This is the generalized eigenvalue/eigenvector problem and is referenced in some mathematical texts.

The Natural Frequency for the Vessel (Empty.) is 27.2982 Hz.

The Natural Frequency for the Vessel (Ope...) is 27.2982 Hz.
