To calculate actual vacuum tank stress for a given working pressure, use that pressure in the calculation and multiply the final result by four. Divide the working pressure by twice the joint efficiency. For an example, with a working pressure of 90 psi and a joint efficiency of 0.9, the result is 50. Divide the tank diameter by the wall thickness.
