JA closed tank 1.8 m in diameter and 2.70 m high is filled to a depth of 2.25 m. The air space is subjected to a pressure of 60 KPa. (a) If the tank material is 2 mm thick, compute the maximum hoop stress that could develop if the tank is rotated about its vertical axis through 120 rpm. (b) If the allowable tensile stress is 75 MPa, determine the maximum angular speed (rpm) that the tank can have without bursting the tank.
