Gulmohar Fil-tech Mechanical Designer Interview Questions, Process, and Tips

Duct design involves considering airflow requirements, material selection, sizing, and layout.

• Determine the airflow requirements for the space or system.

• Select appropriate materials based on factors like temperature, pressure, and corrosion resistance.

• Calculate the duct size based on airflow velocity and pressure drop.

• Design the layout considering space constraints, accessibility, and efficiency.

• Consider factors like n...read more

Different types of pipe sizes used in air header include 1/2 inch, 3/4 inch, 1 inch, and 2 inch.

• Common pipe sizes used in air headers are 1/2 inch, 3/4 inch, 1 inch, and 2 inch.

• Pipe size selection depends on the required air flow rate and pressure drop.

• Larger pipe sizes are used for higher flow rates and to minimize pressure drop.

• Smaller pipe sizes are used for lower flow rates and when space is limited.

• Pipe sizes can ...read more

Different types of pulsing valves used in pulsing

• Diaphragm valves

• Solenoid valves

• Piston valves

• Rotary valves

• Poppet valves

Inlet outlet area calculation is a process of determining the area of the inlet and outlet openings of a system.

• Calculate the area of the inlet and outlet openings using appropriate formulas

• Consider the shape of the openings (e.g., circular, rectangular) and use the corresponding formulas

• Measure the dimensions of the openings accurately to obtain precise results

• Take into account any obstructions or restrictions in the ...read more

A weldment in SolidWorks is a feature that allows users to create and design welded structures.

• Weldments are commonly used in the design of structures such as frames, trusses, and supports.

• They are created by sketching a 2D profile and then using the weldment feature to extrude it along a path.

• Weldments can be made from various materials such as steel, aluminum, or wood.

• They can include different types of welds, such a...read more

To use the same sketch in different planes with different sizes, you can create a base sketch and then use it as a reference to create new sketches.

• Create a base sketch with the desired shape and size

• Use the base sketch as a reference to create new sketches on different planes

• Modify the dimensions and size of the new sketches as needed

• Ensure that the relationships and constraints between the sketches are maintained

• Exam...read more

Different types of filter medium used in pulse jet bag filter.

• Polyester felt

• Polypropylene felt

• Nylon mesh

• Fiberglass

• PTFE membrane

• Acrylic felt

To perform analysis tests in SolidWorks or ANSYS, follow these steps:

• Import the structure into the software

• Define the material properties

• Apply appropriate boundary conditions

• Set up the analysis type (static, dynamic, thermal, etc.)

• Define the loads and constraints

• Mesh the structure

• Run the analysis

• Review the results and interpret them

• Make necessary design modifications based on the analysis
