7. Vessel Analysis -Schedule 40 rupture pressure is 500psi -Schedule 80 rupture pressure is 930psi -Maximum Design stress is 2000psi www.expert4pvc.com/Documents/CharacteristicsOfPVCPipe.pdf -Max service temperature is 140 F, which should be enough for our demonstration purposes. Schedule 80 PVC Pipe Characteristics Bursting and Pressure properties of PVC Pipe

8. Vessel Analysis -Critical Stress-Hoop Stress σ=Pr/t σ=[(80psi)(3in.)]/0.591in. σ=404psi 404psi<2000psi; SF=4.95 -Longitudinal Stress σ=Pr/2t σ=[(80psi)(3in.)]/[(2)(0.591in)] σ=202psi 202psi<2000psi; SF=9.90 P=80 psi r=3.0 in t=0.591 -Stress created is less than bursting stress

9. Cement Glue -Longitudinal Stress=Shear stress seen by the glue] σ=202psi http://www.harvel.com/technical-support-center/installation/joining-techniques/solvent-cementing/joint-strength -Stress seen by the plastic is should allow for no less than a quarter day of curing
