Bechtel Production Graduate Engineer Trainee Interview Questions and Answers

Simple aptitude questions

This is a shortlisting round, and many technically knowledgeable individuals did not qualify for this stage.

Q1. Which flow system is more effective: countercurrent flow or concurrent flow, and what are the reasons for this?
Ans. 
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 ...read more

Q2. What is the procedure for designing a heat exchanger?
Ans. 
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...read more

Q1. Stress Strain Diagram
Ans. 
Stress strain diagram shows the relationship between stress and strain in a material under tension.
• Shows how a material deforms under stress

• Yield point is where material starts to deform permanently

• Ultimate tensile strength is maximum stress material can withstand

• Failure point is where material breaks

• Different materials have different stress strain curves

Q2. Creep vs Fatigue
Ans. 
Creep is the slow, time-dependent deformation of a material under constant load, while fatigue is the weakening of a material due to repeated loading and unloading.
• Creep is a time-dependent phenomenon, while fatigue is a cyclic phenomenon.

• Creep occurs at elevated temperatures, while fatigue can occur at any temperature.

• Creep leads to permanent deformation, while fatigue can lead to crack initiation and propagation.
