The gas storage tank is fabricated by bolting together two half cylindrical thin shells and two hemispherical shells as shown. The tank is designed to withstand a pressure of 4.2 MPa. The tank and the 25-mm-diameter bolts are made from material having an allowable normal stress of 150 MPa and 250 MPa, respectively. The tank has an inner diameter of 4 m. A) Determine the required minimum thickness of the cylindrical shell. B) Determine the required minimum thickness of the hemispherical shell. C) Determine the minimum required number of longitudinal bolts per meter length at each side of the cylindrical shell.

Question
The gas storage tank is fabricated by bolting together two half cylindrical thin shells and two hemispherical shells as shown. The tank is designed to withstand a pressure of 4.2 MPa. The tank and the 25-mm-diameter bolts are made from material having an allowable normal stress of 150 MPa and 250 MPa, respectively. The tank has an inner diameter of 4 m.
A) Determine the required minimum thickness of the cylindrical shell.
B) Determine the required minimum thickness of the hemispherical shell.
C) Determine the minimum required number of longitudinal bolts per meter length at each side of the cylindrical shell.

Transcribed Image Text:The image shows a horizontal cylindrical storage tank typically used for liquids or gases. It is mounted on two supports, which elevate the tank slightly above the ground. The tank has rounded ends, which are referred to as end caps or heads, and features what appears to be reinforcing bands around its circumference. There is a small opening or nozzle on the top, likely used for filling or emptying the tank. The tank rests on a flat surface, possibly concrete. This type of tank is commonly seen in industrial settings or for underground fuel storage.
