Gulbrandsen Interview Questions and Answers

Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.

• Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps: move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps: move fluid parallel to the pump shaft.

• Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, Axial

Classification of materials is the process of categorizing substances based on their properties and characteristics.

• Materials can be classified based on their composition (e.g. metals, polymers, ceramics)

• Materials can also be classified based on their properties (e.g. conductors, insulators, magnetic materials)

• Classification helps in understanding the behavior and applications of different materials

Stress can be classified as acute or chronic, eustress or distress, and as physical, mental, emotional, or environmental.

• Acute vs. Chronic stress

• Eustress vs. Distress

• Physical, Mental, Emotional, Environmental stress

A type of beam is a structural element that carries load primarily in bending.

• Types of beams include cantilever beams, simply supported beams, and fixed beams.

• Beams can be made of materials such as wood, steel, concrete, or composite materials.

• Beams are commonly used in construction to support roofs, floors, and bridges.

Conversion of dimension involves changing the unit of measurement from one form to another.

• Conversion factors are used to convert between different units of measurement.

• Common conversions include inches to centimeters, feet to meters, and pounds to kilograms.

• Remember to multiply or divide by the conversion factor to get the correct result.

Turbines can be classified based on various factors such as type, working fluid, and application.

• Classification based on type: Impulse turbines and Reaction turbines

• Classification based on working fluid: Steam turbines, Gas turbines, and Water turbines

• Classification based on application: Power generation turbines, Marine turbines, and Aircraft turbines

Steel can be classified based on its chemical composition, physical properties, and uses.

• Classification based on chemical composition: carbon steel, alloy steel, stainless steel

• Classification based on physical properties: high carbon steel, low carbon steel, high strength low alloy steel

• Classification based on uses: structural steel, tool steel, stainless steel

• Example: Carbon steel contains mainly carbon and iron, whil
