Paskals Fluid Systems (p) Interview Questions and Answers

The procedure for wind calculation as per IS code involves determining the design wind speed, selecting the appropriate terrain category, and calculating the wind pressure.

• Determine the design wind speed based on the location and height of the structure.

• Select the appropriate terrain category (rural, urban, etc.) as per IS code guidelines.

• Calculate the wind pressure using the formula provided in the IS code.

• Consider fa...read more

A STAAD model for a fixed pole is a structural analysis and design model used to determine the stability and strength of a pole that is fixed in place.

• In a STAAD model for a fixed pole, the pole is typically modeled as a vertical member with fixed supports at the base.

• The model considers factors such as wind loads, dead loads, and any other relevant loads that may act on the pole.

• The analysis helps in determining the s...read more

Key considerations in designing a square base plate

• Ensure the base plate is large enough to support the load without excessive deflection

• Select appropriate material and thickness to meet structural requirements

• Consider the connection details for attaching the base plate to the structure

• Account for any potential corrosion or environmental factors that may affect the base plate

• Include provisions for anchor bolts or other...read more

First angle and third angle symbols are used in engineering drawings to indicate the orientation of the views.

• First angle projection is commonly used in Europe and Asia, where the top view is placed below the front view.

• Third angle projection is commonly used in North America, where the top view is placed above the front view.

• The symbol for first angle projection is a triangle with the number 1 inside, while the symbol...read more

Types of gears include spur, helical, bevel, worm, rack and pinion. Types of bearings include ball, roller, plain, and fluid bearings.

• Types of gears: spur, helical, bevel, worm, rack and pinion

• Types of bearings: ball, roller, plain, fluid

Four common heat treatment processes are annealing, quenching, tempering, and normalizing.

• Annealing involves heating the material to a specific temperature and then slowly cooling it to relieve internal stresses and increase ductility.

• Quenching is a rapid cooling process used to harden materials by forming a martensitic structure.

• Tempering is a heat treatment process that involves reheating the quenched material to a s...read more

Welding joins two metal pieces by melting them together, brazing joins them with a filler metal at lower temperatures, and soldering joins them with an even lower melting point filler metal.

• Welding involves melting the base metals and adding a filler material to create a strong joint, typically at high temperatures.

• Brazing uses a filler metal with a melting point above 450°C but below the melting point of the base meta...read more

A CNC machine works by using computer programs to control the movement of the machine's tools and workpiece to create precision parts.

• CNC machines use computer programs to control the movement of the cutting tools and workpiece.

• The programs are created using CAD/CAM software and converted into G-code instructions.

• The machine reads the G-code instructions and moves the tools along the specified paths to cut and shape th...read more

Flushing is the process of cleaning out a system by forcing fluid through it, while cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure.

• Flushing involves using a fluid to remove contaminants or debris from a system, such as a hydraulic system or a pipeline.

• Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing bubbles to form and collapse, leading t...read more

Materials come in different grades based on their composition, properties, and intended use.

• Materials can be classified into metals, polymers, ceramics, and composites.

• Each material type has different grades based on factors like strength, durability, conductivity, and corrosion resistance.

• Examples include steel grades like 304, 316, and 430, polymer grades like HDPE and PVC, and ceramic grades like alumina and zirconi

Stress is the force applied to a material, while strain is the resulting deformation. Mild steel has a linear stress-strain curve.

• Stress is the force applied to a material per unit area, measured in N/m^2 or Pascals.

• Strain is the resulting deformation of the material, measured as a ratio of the change in length to the original length.

• Mild steel typically has a linear stress-strain curve until it reaches its yield point...read more
