Knexir Consultants Interview Questions, Process, and Tips

Corrosion is the process of deterioration of a material, usually a metal, due to chemical reactions with its environment.

• Corrosion occurs when metal is exposed to oxygen and moisture, leading to the formation of rust.

• Different types of corrosion include galvanic corrosion, pitting corrosion, and stress corrosion cracking.

• Corrosion can weaken structures and equipment, posing safety risks in firefighting scenarios.

• Preven...read more

2-stroke engines have a power stroke every revolution, while 4-stroke engines have a power stroke every other revolution.

• 2-stroke engines have a simpler design with fewer moving parts compared to 4-stroke engines.

• 2-stroke engines require a fuel-oil mixture for lubrication, while 4-stroke engines have a separate oil reservoir.

• 2-stroke engines are lighter and more compact than 4-stroke engines, making them popular in app...read more

The Iron-Carbide (Fe-C) diagram is a graphical representation of the phases and microstructures that form as a function of temperature and carbon content in iron-carbon alloys.

• The Fe-C diagram shows the phases of iron and carbon at different temperatures and carbon concentrations.

• It helps in understanding the microstructure and properties of steel and cast iron.

• The diagram consists of regions such as austenite, ferrite...read more

The different types of sprinklers include upright, pendant, sidewall, and concealed sprinklers.

• Upright sprinklers are installed at the top of a room and spray water upwards.

• Pendant sprinklers hang down from the ceiling and spray water downwards.

• Sidewall sprinklers are mounted on the walls and spray water horizontally.

• Concealed sprinklers are hidden behind a decorative cover and activate when the temperature rises.

Distillation is a process of separating two or more components based on their boiling points.

• VLE (Vapor-Liquid Equilibrium) is a graph that shows the relationship between the vapor and liquid phases of a mixture at different temperatures and pressures.

• The components with lower boiling points will vaporize first and can be collected as the distillate.

• The components with higher boiling points will remain in the distillat...read more

Line sizing involves determining the appropriate diameter of a pipeline for a given flow rate and fluid properties.

• Determine the required flow rate and fluid properties

• Calculate the Reynolds number to determine the flow regime

• Select an appropriate friction factor based on the flow regime

• Use the Darcy-Weisbach equation to calculate the pressure drop

• Choose a pipe diameter that satisfies the pressure drop and velocity con
