Tecnimont Graduate 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. WHAT IS BLDC MOTOR
Ans. 
BLDC motor stands for Brushless DC motor, which is a type of electric motor that operates without the need for brushes to transfer electrical current.
• BLDC motors use electronic commutation instead of brushes to control the motor's operation.

• They are more efficient, reliable, and have a longer lifespan compared to brushed DC motors.

• BLDC motors are commonly used in applications such as electric vehicles, drones, and indu

General Chemical engineering question related to fluid mechanics and thermodynamics.

Q1. Type of pump, cavitation, pump.curve
Ans. 
Different types of pumps include centrifugal, reciprocating, and rotary pumps. Cavitation occurs when low pressure causes bubbles to form in the pump, leading to damage. Pump curve shows the relationship between flow rate and head.
• Types of pumps: centrifugal, reciprocating, rotary

• Cavitation: occurs when low pressure causes bubbles to form in the pump, leading to damage

• Pump curve: shows the relationship between flow rat
