Web1. A thin walled cylinder is 80 mm mean diameter with a wall 1 mm thick. Calculate the longitudinal and circumferential stresses when the inside pressure is 500 kPa larger than on the outside. (Answers 10 MPa and 20 MPa). 2. Calculate the wall thickness required for a thin walled cylinder which must withstand a Web8.4.1.1 Thick Cylindrical Pressure Vessels Under Internal Pressure Only If p o = 0, Equations (8-35) and (8-36) reduce to F r = a 2 p i b 2 − a 2 ( 1 − b 2 r 2) (8-38) and F t = a 2 p i b 2 − a 2 ( 1 + b 2 r 2) (8-39) Both of these stresses have maximum magnitudes at r = a.

Webfound in thick walled cylindrical pressure vessels. In the most general case the vessel is subject to both internal and external pressures. Most vessels also have closed ends - this results in an axial stress component. Principal stresses at radius r : And, if the ends are closed, 2 2 2 σ1 =σθ=−K +C/r: σ=σr =−K +C/r σ3 =σaxial =−K ... WebThe pressure in a thin walled tube with diameter 0.3 mand thickness 0.001 mis 1000 kPa (10 bar). The hoop stress can be calculated σh= (1000 kPa) (0.3 m) / (2 (0.001 m)) = 150000kPa = 150MPa The longitudinal stress … cheap disability toys
