We want to select a steel pipe with an inside diameter of at least 1ft that will withstand an internal pressure of 1,000psig. The steel to be used has a maximum allowable tensile stress of 40,000psi but, to allow for a safety factor of 4, we design for a maximum stress of 10,000psi. (a) How thick must the pipe walls be if the steel pipe has an inner diameter of 1ft ? (b) What is the initial selection of the steel pipe that meets the diameter and thickness requirement? (You will need to use the pipe schedule table in Perry's Chemical Engineers' Handbook to solve this problem. Go the LaTech library website: http://www.latech.edu/library/ and search for "Perry's Chemical Engineers' Handbook". Click on the "eBook Full Text" in the first result. The table for steel pipe properties (Table 10-22) begins on page 78 of Section 10: Transport and Storage of Fluids.) (c) Confirm that the pipe selected in part (b) is meets both the diameter and pressure specifications by calculating the maximum pressure that this pipe can withstand
