10+ Engineering Officer Interview Questions and Answers

Defects in welding are imperfections or flaws that occur during the welding process.

• Common defects include porosity, undercutting, incomplete fusion, and cracks.

• Porosity is caused by gas entrapment and can be mitigated by using proper shielding gas and cleaning the base metal.

• Undercutting is a groove formation at the weld toe and can be reduced by adjusting welding parameters.

• Incomplete fusion occurs when the weld metal does not properly fuse with the base metal and can be pr...read more

Conductivity of purified water can be maintained by removing impurities and controlling temperature.

One metre has 1000 MM

• 1 metre = 1000 millimetres

• MM is the abbreviation for millimetre

• Metric system is based on multiples of 10

To maintain the RH of an area, proper ventilation, dehumidification, and moisture control measures should be implemented.

• Ensure proper ventilation to allow for air circulation and prevent moisture buildup

• Use dehumidifiers to remove excess moisture from the air

• Implement moisture control measures such as sealing cracks and leaks

• Monitor RH levels regularly and adjust ventilation and dehumidification systems accordingly

1 KM has 1,000,000 MM

• 1 KM = 1000 M

• 1 M = 1000 MM

• 1 KM = 1000 x 1000 MM = 1,000,000 MM

RMG capacity refers to the maximum amount of material that can be processed by a rotary dryer.

• RMG stands for Rotary Dryer

• Capacity varies depending on the size and design of the dryer

• Typical RMG capacities range from a few hundred pounds to several tons

• Factors that affect capacity include material type, moisture content, and desired output

Troubleshooting of HVAC systems involves identifying and resolving issues related to heating, ventilation, and air conditioning systems.

• Identify the problem by observing and analyzing the system's performance.

• Check for any visible signs of damage or malfunctioning components.

• Inspect and test individual components such as motors, fans, filters, and thermostats.

• Use diagnostic tools and equipment to measure temperature, pressure, and airflow.

• Refer to system manuals and documenta...read more

A reactor is a device used to contain and control a nuclear chain reaction.

• Reactors are used in nuclear power plants to generate electricity.

• They work by using controlled nuclear fission to produce heat, which is then used to create steam and drive turbines.

• There are different types of reactors, such as pressurized water reactors (PWR) and boiling water reactors (BWR).

Pumps are devices used to move fluids (liquids or gases) by mechanical action.

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

• Positive displacement pumps: trap a fixed amount of fluid and then force it into a discharge pipe.

• Diaphragm pumps: use a flexible diaphragm to move fluid.

• Gear pumps: use interlocking gears to move fluid.

• Peristaltic pumps: use rotating rollers to squeeze a flexible tube.

• Axial flow pumps: move fluid parallel to the pump sha...read more

Patrolling points can be checked by physically visiting each point on a regular basis to ensure security and safety.

• Create a list of all patrolling points

• Assign specific officers to check each point

• Establish a schedule for regular patrols

• Use technology such as GPS tracking to monitor patrol routes

• Document any issues or incidents encountered during patrols

HVAC works by controlling the temperature, humidity, and air quality in a building through heating, ventilation, and air conditioning systems.

• HVAC systems use a combination of heating, cooling, and ventilation to maintain a comfortable indoor environment.

• Heating is typically provided by a furnace or boiler, while cooling is achieved through air conditioning units or heat pumps.

• Ventilation involves exchanging indoor and outdoor air to improve air quality and remove pollutants....read more

Types of maintenance include preventive, corrective, predictive, and proactive maintenance.

• Preventive maintenance involves regular inspections and maintenance to prevent breakdowns.

• Corrective maintenance is performed after a failure occurs to restore equipment to working condition.

• Predictive maintenance uses data and analytics to predict when maintenance is needed.

• Proactive maintenance involves identifying and addressing potential issues before they cause problems.

• Examples: c...read more
