This is a shortlisting round, and many technically knowledgeable individuals did not qualify for this stage.
Countercurrent flow is more effective due to increased concentration gradient and better utilization of resources.
Countercurrent flow allows for a greater concentration gradient between the two fluids, leading to more efficient mass transfer.
Countercurrent flow also allows for better utilization of resources as the fluids are in contact for a longer period of time.
Concurrent flow, on the other hand, results in a lower ...
The procedure for designing a heat exchanger involves determining heat transfer requirements, selecting appropriate materials, designing the geometry, and analyzing performance.
Determine the heat transfer requirements based on the fluids involved, flow rates, temperatures, and desired heat transfer rate.
Select appropriate materials for the heat exchanger based on compatibility with the fluids, operating conditions, and...

Plastic viscosity is the measure of a fluid's resistance to flow, important in artificial lift operations.
Plastic viscosity is a rheological property of fluids, indicating how easily a fluid can flow under stress.
In artificial lift operations, understanding plastic viscosity helps in selecting the right pumping equipment and optimizing production.
Higher plastic viscosity can lead to increased pressure drop in the wellb...

Graph based question. Duration: 45 mins
Various sensors used in oil and gas industries include pressure sensors, temperature sensors, flow sensors, level sensors, and gas detectors.
Pressure sensors - used to measure pressure in pipelines and equipment.
Temperature sensors - monitor temperature levels in various processes.
Flow sensors - measure the flow rate of liquids or gases in pipelines.
Level sensors - detect the level of liquids in tanks or vessels.
Gas de...
HAZOP stands for Hazard and Operability Study, while HAZID stands for Hazard Identification.
HAZOP is a systematic method to identify potential hazards and operability issues in a process plant.
HAZID is a process used to identify hazards in a facility or operation before they become accidents.
Both HAZOP and HAZID are important tools in risk assessment and management in engineering projects.
P, PI, PID are types of controllers used in process control to regulate the output based on the input.
P stands for Proportional controller, which adjusts the output based on the error signal.
PI stands for Proportional-Integral controller, which not only adjusts based on error signal but also integrates the error over time.
PID stands for Proportional-Integral-Derivative controller, which adjusts based on error signal, i...
Digital Electronics is a branch of electronics that deals with digital signals and systems.
Deals with digital signals (0s and 1s)
Involves logic gates, flip-flops, and digital circuits
Used in computers, calculators, digital watches, etc.
Binary arithmetic and Boolean algebra are fundamental concepts
Level sensor, flow sensor, and temperature sensor are devices used to measure different physical parameters in various industries.
Level sensor measures the level of a substance in a container or tank, such as liquid level sensors in water tanks.
Flow sensor measures the flow rate of a fluid, like a flow meter in a pipeline.
Temperature sensor measures the temperature of a system or environment, for example, a thermocoupl

Interview questions for Structural Engineer
For irregular shape, find volume and multiply by unit weight to get weight. Divide moment of each part by total weight to get COG.
To calculate force required for COG shift, use moment equation. Sum of moments about any point should be equal to zero.
For SFD and BMD, use equations of equilibrium and moment. Draw free body diagram to show all forces acting on the portal.

Dynamic and static analysis of structures and foundations is essential for ensuring their stability and safety.
Dynamic analysis involves studying the behavior of structures under dynamic loads such as earthquakes or wind.
Static analysis focuses on the response of structures to static loads like gravity or applied forces.
Both analyses help in determining the structural integrity, performance, and design optimization.
