Resource type: Equation
Description: Gives the value of stress at the inner radius of a cylindrical shaped container using a thin assumption that the radius is at least ten times the wall thickness.

TeX format: \sigma_h = \frac{Pr}{t}

σh {\sigma_h} = Hoop stress (Pa) {Pa}
P {P} = Internal pressure (Pa) {Pa}
r {r} = Cylinder radius (m) {m}
t {t} = Cylinder wall thickness (m) {m}
Keywords: pressure • vessel • tank • container • hoop • stress • steam • boiler
