10+ Interview Questions and Answers

Cover depth is the depth at which reinforcement is provided in concrete structures.

• Cover depth protects the reinforcement from corrosion and fire damage.

• It also helps in providing durability and strength to the structure.

• The amount of cover depth depends on the type of structure and its exposure to environmental factors.

• For example, in a bridge exposed to saltwater, a cover depth of 75mm may be required.

• In a building, a cover depth of 25mm may be sufficient.

• Cover depth is usu...read more

Explanation on how to calculate kVA to kW to hp and why induction motor is not self-starting.

• kVA to kW conversion: kW = kVA x power factor

• kW to hp conversion: hp = kW x 1.34

• Induction motor not self-starting due to absence of rotating magnetic field at start

• Starting methods include using external means to create rotating magnetic field or adding starting winding

• Examples of starting methods: star-delta starter, auto transformer starter, capacitor start induction run motor

An incident is an unplanned event that could have resulted in harm, while an accident is an incident that actually caused harm.

• Incidents are events that have the potential to cause harm, but do not necessarily result in harm.

• Accidents are incidents that have resulted in harm or injury.

• Incidents can be used as a learning opportunity to prevent accidents from happening in the future.

• Examples of incidents include near misses, equipment malfunctions, and unsafe acts.

• Examples of a...read more

Pipeline is a process of transporting fluids or gases from one place to another through a series of interconnected pipes.

• Pipeline involves designing, constructing, and maintaining a network of pipes.

• It is used for transportation of oil, gas, water, and other fluids.

• The pipeline system includes pumps, valves, and control systems to regulate the flow of fluids.

• Pipeline construction involves excavation, welding, coating, and testing of pipes.

• Maintenance includes regular inspecti...read more
