 Thickness for a cylinder Post Reply Engineering Forum
 Posted by: abid ® 05/08/2009, 00:56:34 Author Profile eMail author Edit I designing a cylinder for cycle hand pump. I have the internal pressure, inside diameter, length of cylinder. Now I want to calculate the thickness of the cylinder. Please guide me how to calculate it. Thanks
