Angelique International Project Engineer Interview Questions and Answers

Bending moment is a measure of the bending force applied to a structural element. Weight of MS pipe and bar can vary based on size and density of construction materials.

• Bending moment is a measure of the bending force experienced by a structural element.

• It is calculated by multiplying the force applied to the element by the distance from the point of force application to the point of interest.

• The weight of MS pipe and ...read more

Pump head loss calculation parameters include friction loss, elevation change, velocity head, and fittings.

• Friction loss due to pipe roughness

• Elevation change between inlet and outlet

• Velocity head due to fluid velocity

• Losses from fittings like elbows, tees, and valves

AHU components refer to the various parts of an Air Handling Unit that work together to regulate and circulate air in a building.

• Filters - to remove dust and particles from the air

• Coils - for heating or cooling the air

• Fans - to circulate the air

• Dampers - to control the flow of air

• Humidifiers/dehumidifiers - to adjust the humidity levels

Centrifugal blowers are commonly used in AHUs for their efficiency and ability to handle high volumes of air.

• Centrifugal blowers are preferred for AHUs due to their ability to handle high volumes of air efficiently.

• They are more energy efficient compared to other types of blowers.

• Examples of centrifugal blowers commonly used in AHUs include forward curved, backward inclined, and airfoil designs.

Primary pump is the main pump responsible for the majority of the pumping work, while secondary pump is a backup pump used in case the primary pump fails.

• Primary pump is the main pump in a system, while secondary pump is a backup pump.

• Primary pump is responsible for the majority of the pumping work, while secondary pump is used only when needed.

• Examples: In a heating system, the primary pump circulates hot water throug...read more

AHU valve connection refers to the connection of valves in an air handling unit for controlling the flow of air.

• AHU valve connection is essential for regulating the flow of air in an air handling unit.

• Valves are typically connected to the AHU ductwork to control the amount of air entering or exiting the unit.

• Properly connected valves ensure efficient operation of the AHU system.

• Examples of AHU valves include damper val

Chilled water pipe size requirements depend on flow rate, pressure drop, material, insulation, and system design.

• Flow rate: Determine the required flow rate of chilled water in the system.

• Pressure drop: Calculate the pressure drop to ensure efficient operation.

• Material: Select appropriate pipe material based on temperature and pressure requirements.

• Insulation: Insulate the pipes to prevent heat gain or loss.

• System desi...read more

The chiller connection refers to the method by which a chiller unit is connected to a building's HVAC system.

• Chiller connection typically involves piping to transport chilled water from the chiller to the building's air handling units.

• The connection may also include electrical wiring for power supply and control signals.

• Proper chiller connection is crucial for efficient cooling and proper functioning of the HVAC system

The current market labour rate and material price can vary depending on location, demand, and supply.

• Labour rates can be influenced by factors such as skill level, experience, and union agreements.

• Material prices can fluctuate due to changes in raw material costs, transportation expenses, and market demand.

• It is important to regularly monitor market trends and industry news to stay informed about labour rates and mater
