TCE Senior Engineer Interview Questions and Answers

Surging is a phenomenon in which a system experiences rapid and temporary increases in pressure or flow rate.

• Surging can occur in various systems such as pipelines, compressors, pumps, and turbines.

• It is often caused by sudden changes in demand, equipment malfunctions, or improper system design.

• Surging can lead to damage to equipment, reduced efficiency, and safety hazards.

• Examples include water hammer in pipelines and...read more

Froude number is a dimensionless number used to quantify the influence of gravity on fluid flow.

• Froude number is defined as the ratio of inertia force to gravitational force in a fluid flow.

• It is used to determine the type of flow (subcritical, critical, or supercritical) in open channel flow.

• Froude number is calculated as Fr = V / sqrt(g * d), where V is velocity, g is acceleration due to gravity, and d is depth of fl...read more

Weeping is the process of fluid leaking out of a solid material, often due to damage or excess moisture.

• Weeping can occur in materials such as wood, concrete, and metal.

• It is often a sign of structural damage or deterioration.

• Examples include water weeping from a crack in a wall or oil weeping from a car engine.

• Weeping can also refer to the shedding of tears in humans and animals.

A basic PFD of a WTP plant including feed quality and sensors.

• Include feed quality parameters such as turbidity, pH, temperature, and flow rate

• Include sensors for monitoring parameters like chlorine levels, pressure, and conductivity

• Show the flow of water through various treatment processes like coagulation, flocculation, sedimentation, filtration, and disinfection

Process checks in line testing of a 6inch dia pigging line and associated calculations

• Pressure testing to ensure integrity of the line

• Flow testing to check for blockages or restrictions

• Calibration of pigging equipment for accurate results

• Calculations involve pressure drop, flow rate, and pigging efficiency

• Recording and analyzing data for future reference

Load cases in STAAD are used for qualification purposes to ensure structural safety.

• Load cases are combinations of loads that a structure may experience during its lifetime.

• Qualification load cases are used to ensure that the structure can withstand the maximum expected loads.

• Examples of load cases include dead load, live load, wind load, seismic load, and temperature load.

• Each load case is analyzed separately to deter...read more

Stiffness value refers to the resistance of an object to deformation under an applied force.

• Stiffness is a measure of how much force is required to deform an object.

• It is often used in engineering to describe the rigidity of a material or structure.

• Stiffness can be calculated using Hooke's Law, which states that the force required to deform an object is proportional to the displacement.

• For example, a steel beam is stif...read more

The rate of sinking wells varies based on soil conditions, equipment, and project specifications.

• Typical sinking rates range from 0.5 to 2 meters per day, depending on soil type.

• In soft clay, wells may sink faster due to lower resistance.

• Using advanced drilling techniques can increase efficiency and speed.

• For example, a well in sandy soil may require slower sinking rates to ensure stability.
