Where used:
E = Modulus of Elasticity (lbs/in2)
v = Poisson's ratio
W = Weight of liquid (lbs)
δ = Density (lbs/in3
σ1,2 = Stress, (lbs/in2)
R1 = Radius (in)
R2 = Radius (in)
t = Wall thickness (in)
d = Liquid level (in)
y = Vertical level from bottom of vessel (in)
θ = Angle (deg.)
ψ = Rotation of a meridian from its unloaded position, positive when that meridional rotation represents an increase in ΔR when y or θ increases;
