Note: There is a discontinuity in the rate of increase in fluid pressure at the top of the liquid. This leads to some bending in this region and is indicated by a discrepancy in the two expressions for the meridional slope at y = d.)

Where used:
E = Modulus of Elasticity (lbs/in2)
v = Poisson's ratio
δ = Liquid density (lbs/in3)
σ1,2 = stress, (lbs/in2)
y = At some level of the cone (in)
d = Liquid fill level, (in)
t = Wall thickness (in)
α = 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;
