A spherical pressured tank of radius 1.5 m is being designed by a civil engineer to be a storage of natural gas from the Malampaya gas field. The gas it will contain is subject to a change in temperature of 295 °C with an internal pressure of 20 MPa. The final design of the tank gives a 9 mm wall thickness with a Poisson's ratio of 0.28. Use a - 11.7x10°/°C and E- 200 GPa. a. Determine the tangential/longitudinal stress. b. Change in radius.
