1. Introduction to Pressure Vessels

Try these first

1. 1.

   What is a pressure vessel?

   Hint

   Think about where you might find gas or steam.

2. 2.

   Name one type of thin-walled pressure vessel.

   Hint

   Consider common household items.

3. 3.

   What is the main purpose of a pressure vessel?

   • Store liquids at ambient pressure
   • Contain high-pressure fluids
   • Modify liquid properties

   Hint

   Consider what happens to gases when compressed.

4. 4.

   True or False: Thick-walled cylinders use simpler equations than thin-walled cylinders.

   • True
   • False

   Hint

   Review the difference in thickness versus radius.

5. 5.

   A cylindrical pressure vessel has an internal radius of 0.5 m and a wall thickness of 0.02 m. Calculate the hoop stress if the internal pressure is 2 MPa.

   Hint

   Remember to convert pressure units where necessary.

6. 6.

   A boiler operates at a mechanical stress of 80 MPa and a thermal stress of 20 MPa. Calculate total stress.

   Hint

   Just add the two stresses together for the total.
