Determine the stresses in the shell:
A cylindrical boiler is 2.5 m in diameter and 20 mm in thickness and it carries steam at a pressure of 1.0 N/mm2. Determine the stresses in the shell.
Solution
Diameter of the shell, d = 2.5 m = 2500 mm. Thickness of the shell, t = 20 mm.
Internal pressure, p = 1.0 N/mm2.
∴ Longitudinal stress pd /4t = (1.0 × 2500 )/(4 × 20 )= 31.25 N/mm2 (tensile)
∴ Hoop stress pd /2t = 1.0 × 2500 /2 × 20= 62.5 0 N/mm2 (tensile)
