Weight of vessels

W0 = mechanical work imparted to the fluid system from an outside source, ft 1 lbf/lbm Wv = weight of vessel, lbm, see Table 6... 

Weight of vessel and normal contents under operating or test conditions, including additional pressure due to static head of liquids.

Cv = coefficient from Table 3-9b Ca = coefficient from Table 3-9a S =site coefficient (1.0-2.0 based on soil profile) Wo = operating weight of vessel, lb w = uniform weight of vessel or stack, Ib/ft F( —lateral force applied at top of structure, lb Ft==0.07TV or 0.25V whichever is less, or =0, if T <0.7 sec H = overall height of vessel, ft D = outside diameter of vessel, ft T = period of vibration, sec (see Figure 3-7) y = deflection, in.
