Apressure cylinder has a diameter of 150-mm and has a 6-mm wall thickness. what pressure can this vessel carry if the maximum shear stress is not to exceed 25 mpa?

p = 8N/mm2

Explanation:

given data ;

diameter of cylinder =  150 mm

thickness of cylinder = 6 mm

maximum shear stress =  25 MPa

we know that

hoop stress is given as =

axial stress is given as =

maximum shear stress = (hoop stress - axial stress)/2

putting both stress value to get required pressure

t = 6 mm

d = 150 mm

therefore we have pressure

p = 8N/mm2

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
