Hemispherical end caps are welded to a cylindrical body to form a propane storage tank. The tank has an inside diamater of 100 cm and will be subjected to a maximum internal pressure of 820 kPa. The allowable tensile stress in the wall is 83 MPa, and the allowable tensile stress in the weld is 55 MPa.
a. Determine the minimum wall thickness of the cylindrical part of the tank.
b. Determine the minimum wall thickness of the hemispherical end caps.
c. Determine the minimum thickness of the welds.
A water line to a home is usually 3⁄4" copper tube. What is the flow rate that can be delivered and still maintain laminar flow in the tube?
