Calculations for Front and Side Glass Panels:

The thickness of the glass (t) is proportional to the (square root of width factor (beta) x height (H) cubed x 0.00001 / allowable bending stress (B)).

so; t = SQR (beta x H^3 x 0.00001 / 5.05) in mm.

Select beta and alpha from the previous chart based on the length to height ratio.

The deflection of the glass is proportional to (alpha x water pressure (p) x 0.000001 x Height^4) / (Modulus of elasticity (E) x Thickness (t) cubed).

Deflection = (Alpha x p x 0.000001 x H^4) / (69000 x t^3) in mm.

Example: (Warren’s new tank)

Aquarium Length = 3000mm
Aquarium Height = 950mm
Safety Factor = 3.8 L/H>3 therefore Beta = 0.37 and Alpha = 0.067

p = 950 x 10 = 9500N/m²

Side Thickness:
t = SQR (0.37 x 950^3 x 0.00001 / 5.05)

= 25.06mm

Deflection = (0.067 x 9500 x 0.000001 x 950^4) / (69000 x 25^3)

= 0.48mm
