Classify pressure vessels as per IS 2825 and explain the significance of design stress and joint efficiency.
Discuss the general steps in designing a cylindrical shell for internal pressure including selection of corrosion allowance, testing and code requirements.
Explain the area-for-area method for sizing nozzle reinforcement pads with a neat sketch.
A nozzle is welded to a cylindrical shell of a pressure vessel. State the data required and outline the complete design procedure to check adequacy of reinforcement using the area-replacement method.
With neat sketches, discuss the different types of standard flanges and flange facings used in process vessels, highlighting their selection criteria.
Explain the classification of storage tanks as per IS 803 and define a Class A storage tank.
Tank Diameter: 30 m Tank height: 18 m Sp. Gr. of liquid: 1.18 Conical roof slope: permissible 1 in. 5 Superimposed load - 125 kg/m² Material – carbon steel (structural) Permissible stress : 980 kgf/cm² Density of plate material : 7800 kg/m³ Modulus of elasticity: 2 x 106 kg/cm² Standard plate size = 1.8 m width x 6.3 m length Design the shell and bottom. Verify that self-supporting conical roof can work for this storage tank or not Conical roof slope: permissible 1 in.
State the functions of floating roofs in storage tanks and list different types of floating roofs.
Explain the design steps and precautions for shell and bottom plates for a fixed-roof tank storing a corrosive liquid, considering corrosion allowance and fabrication aspects.
Describe the complete design procedure for a column-supported conical roof, including selection of columns, rafters, girders and roof curb angle.
Classify agitators and discuss the selection criteria for choosing a suitable agitator for liquid–liquid mixing.
A flat-blade turbine agitator with six blades is installed in a baffled tank. Describe the stepwise procedure to determine power requirement, shaft diameter and blade thickness for safe operation under given fluid properties.
List the different types of jackets used on reaction vessels and mention two advantages of a half-coil jacket over a plain jacket.
Find out the thickness of shell of the reactor & thickness of jacket for the following three available options:
Write a short note on saddle supports, indicating when they are preferred over other support types.
Explain the design criteria for skirt supports for tall distillation columns, including allowable stresses and load combinations.
A tray distillation column operates at elevated temperature and pressure. Outline the procedure for determining shell thickness at various heights considering internal pressure, dead load and wind load.
Explain the design procedure for bracket supports for a vertical cylindrical vessel installed outdoors.
Discuss the design steps for skirt and base plate including anchor bolts for a tall column subject to combined dead load and wind load, and comment on possible failure modes.
