JOINT EFFICIENCY
JOINT EFFICIENCY
Longitudinal stress is given by,
If A is the gross area and Aeff is the effective resisting area then, Efficiency = Aeff/A
If η c=Efficiency of circumferential joint Efficiency = Aeff/A
Bursting force = (π d2/4)p
Resisting force = σL ×A′eff = σL ×ηc ×A′ = σL ×ηc ×π d t
Where η L=Efficiency of circumferential joint
Bursting force = Resisting force
Max permissible pressure in the tank, p = 2.88 MPa.
Sample Problem # 2
(ii) To find the permissible pressure for an internal diameter of 1.5m: (d=1.5m=1500mm)
