Consider a thin-walled cylindrical pipe with a 1.00" inner diameter that is used to transport pressurized steam. the gauge pressure (p) of steam within the pipe is 10.3 mpa. a. compute the minimum required wall thickness (mm) for each of the following metal alloys. assume a factor of safety of 2. you can use excel to calculate thickness for all metals, but show your work for at least one. b. which of the alloys below will be the least expensive in satisfying the above engineering requirements
