Aluminum Pipe - Pressure Rating Calculation

The calculator can calculate the pressure rating or allowable stress or wall thickness or pipe outside diameter for aluminum pipe as per selection given appropriate values.

I want to calculate
Allowable Stress(S) = P
Wall Thickness(t) = m
Pipe Outside Diameter(D) = m
Pressure Rating(PR) = P
Pressure Rating:PR=2St/D,
Allowable Stress:S=PRxD/2t,
Wall Thickness:t=PRxD/2S,
Pipe Outside Diameter:D=2St/PR
PR = Pressure Rating,
S = Allowable Stress,
t = Wall Thickness,
D = Pipe Outside Diameter.
