(1) Ellipsoidal Head #1 limits the UG-99(b) stress ratio.
(2) The zero degree angular position is assumed to be up, and the test liquidheight is assumed to the top-most flange.
The field test condition has not been investigated.
The test temperature of 21.11 °C is warmer than the minimum recommended temperature of -12 °C so the brittlefracture provision of UG-99(h) has been met.

s= 2*1,203.26*1*6.33 / (1*273.05 - 2*6.33*(1 - 0.1)) - 0= 58.22 kgf /cm
