Worley Junior Process Engineer Interview Questions, Process, and Tips

It was quite easy, basic quant and analytical aptitude. Questions were also asked from your core sector, which are manageable.

Group of 5 members were formed and current topics were discussed

Q1. Explain Heat duty of heat echanger
Ans. 
Heat duty of a heat exchanger refers to the amount of heat transferred between the hot and cold fluids.
• Heat duty is the heat transfer rate or the amount of heat energy transferred per unit time.

• It is calculated by multiplying the mass flow rate of the fluid by the specific heat capacity and the temperature difference between the hot and cold fluids.

• The heat duty determines the size and design of the heat exchanger.

Q2. What is bernoullis principle
Ans. 
Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases.
• Bernoulli's principle relates to the conservation of energy in fluid flow.

• It states that as the speed of a fluid increases, its pressure decreases.

• This principle is applicable to various fluid dynamics phenomena, such as airflow over an airplane wing or water flow through a pipe.

• It explains how an airplane wing generates lift by...read more

Q3. Explain grashoff number
Ans. 
The Grashoff number is a dimensionless number used in fluid dynamics to determine the dominance of buoyancy forces over viscous forces in a fluid flow.
• The Grashoff number is defined as the product of the ratio of buoyancy forces to viscous forces and the square of the ratio of characteristic length to kinematic viscosity.

• It is used to analyze natural convection flows and is particularly important in heat transfer appli...read more

Q5. Design ofdistillationcoloumns
Ans. 
Design of distillation columns
• Distillation columns are used to separate mixtures of liquids based on their boiling points

• The design of a distillation column involves determining the number of trays or packing, column diameter, and reflux ratio

• The design is influenced by factors such as the desired separation efficiency, feed composition, and operating pressure

• Different types of distillation columns include packed colum...read more
