Thick Pipes. Let S = the cohesive strength of the metal per square Inch. P = the internal pressure per square inch, in the same terms as S. R=the radius of the inside of the pipe in inches. T=the thickness of the metal in inches. For cast iron may take S as 7, 142 tons, or 16, ...000 Ibs. Per square inch ; for lead as 2, 745 Ibs. RxP Then T = SxT S = Thin Pipes.
