A 50 inch diameter steel pipe with a thickness of 0.25 inches, carries oil of specific gravity of 0.822 under a head of 350 ft of oil. Compute the pressure inside the pipe in psi, circumferential stress, Compute the thickness of steel required to carry a pressure of 220 psi with a hoop stress of 18,000 psi.
Homework Answers
daimeter of pipe ÷12= 50÷12 =4.16 in > 0.25 in.so,pipe is thin cylinder.
specific gravity of oil = 0.822
density of oil = 0.822×1 = 0.822 g/cc
=0.822×0.036127 =0.02969 lb/in^3
pressure inside pipe p = 
gh =0.02969×3.8622×350×12=481.608 psi
Hoop stress = pd÷2t =(481.608×50)÷(2×0.25)
= 48160.8 psi
given that pressure p =220 psi
hoop stress = 18000 psi
we know that hoop stress = pd÷2t
= (220×50)÷(2×t)=18000
t = (220×50)÷(2×18000)
thickness of pipe t = 0.3055 inches.

As shown, a pipe serves as a short column. The 4 - inch diameter steel pipe has 6 in x 6 in in steel plates welded to its ends.The top column plate carries a 5-1/8" wide wood beam that exerts an axial load on the column of 11,800 lbs., including the weight of the beam. The bottom plate bears on a concrete pad. The weight of the column is 53.5 lbs. Compressive stress in the steel must not exceed 20,000...

A pipe with an inner diameter of 8 inches (0.67 ft) carries water (ρ = 62.4 lbm/ft3, μ = 6.72 x 10-4 lbm/ft ⋅s) horizontally at a flow rate of 3.1 ft3/s. The pipe has been in service for a very long time, so the wall surface has become fairly rough (ε = 0.008 inches). The pipe is 1550 ft long. A) Calculate ΔP over the pipe length in psi B) Suppose the old pipe is now replaced with a...
