2. Why temperature isconsideredasdesignloading? How iteffectthe designof equipment?
3. A equipmentismade of three parts.MDMT of parts are 20°C, 0°C & -20°C. What shall be the
MDMT of the equipment?
4. A equipmentismade of three parts.MAWP of parts are 130 MPa, 100Mpa & 80 MPa. What
shall be the MAWP of the equipment?
5. MAWP of a vertical vessel isalwayscalculatedand indicatedatthe topmost part of vessel,
Why?
6. Consideracylindrical shellwithaopeningof 100 mm ID. The requiredthicknessfor shell is6
mm and providedthicknessis12mm. Whetherthe openingneedsreinforcement?
7. If a vessel ishavinginternal pressure of 20 bar (a) and external pressure of 1bar (a),for which
internal andexternal pressure the vessel shallbe designed?

Considerthe vesselasshowninabove diagram.Followingdataare available:
i) Inside diameter:Di mm
ii) Thickness:tmm
iii) Densityof constructionmaterial:dg/cm3
iv) Mass of the vessel:mKg
v) Length:L mm
Compute the stressdue todeadweightat the line A__A.
Alsocompute the stressdue todeadweightat the line A__A , whenthe vessel ishalf filledwithwater.
