A liquid of volumetric thermal expansion coefficient = and bulk modulus B is filled in a spherical tank of negligible heat expansion coefficient. Its radius is R and wall thickness is 't' (t <<R). When the temperature of the liquid is raised by , the tensile stress developed in the walls of the tank is :
Options:
Answer:
A
Solution:
Pressure rise is Bγθ. Thin spherical-vessel stress is pR/(2t).
Thus stress=BγθR/(2t).
