10+ RBT Computers Interview Questions and Answers

The inverse of density is specific volume.

• Specific volume is the reciprocal of density.

• It represents the volume occupied by a unit mass of a substance.

• Specific volume is commonly used in thermodynamics and fluid mechanics.

• For example, the specific volume of water at 25°C and atmospheric pressure is approximately 0.001 m^3/kg.

Different modes of heat transfer include conduction, convection, and radiation.

• Conduction: Heat transfer through direct contact between objects or substances.

• Convection: Heat transfer through the movement of fluids or gases.

• Radiation: Heat transfer through electromagnetic waves, such as from the sun.

• Examples: Touching a hot pan (conduction), boiling water (convection), feeling the warmth of the sun (radiation).

Bearings are used to reduce friction between two moving parts. There are several types of bearings.

• Bearings are used to support and reduce friction between two moving parts

• They come in different types such as ball bearings, roller bearings, and plain bearings

• Ball bearings are used in applications with low load and high speed

• Roller bearings are used in applications with high load and low speed

• Plain bearings are used in applications with high load and low speed where lubricatio...read more

Gearbox is a mechanical device that transmits power from an engine to the wheels by changing the speed and torque of the output shaft.

• It provides torque multiplication and speed reduction.

• It allows the engine to operate at its most efficient speed.

• It enables the vehicle to move at different speeds and climb hills.

• It protects the engine and transmission from damage by absorbing shock loads.

• Types of gearbox include manual, automatic, and continuously variable transmission (CVT)...read more

Neutral wire is typically white or gray, while ground wire is typically green or bare copper.

• Neutral wire is usually white or gray in color.

• Ground wire is typically green or bare copper.

• In some cases, ground wire may also be green with a yellow stripe.

• It is important to always follow local electrical codes when identifying wire colors.

The question covers slope percentage calculation of kiln, tan value in oil analysis, and material and manpower handling.

• For slope percentage calculation of kiln, we need to measure the height and length of the kiln and use the formula tan(theta) = height/length.

• Tan value in oil analysis is used to determine the acidity of the oil. It is calculated by dividing the acid number by the saponification number.

• Material and manpower handling involves managing the flow of materials an...read more

Silica gel in transformers is used as a drying agent to absorb moisture and prevent the formation of harmful gases.

• Silica gel is a desiccant that absorbs moisture from the air to keep the transformer dry.

• It helps prevent the formation of harmful gases like hydrogen and carbon monoxide, which can degrade the transformer insulation.

• Silica gel is typically placed in a breather to absorb moisture as air enters and exits the transformer.

• Regular monitoring and replacement of silica...read more

A ground and motorized circuit breaker diagram includes components like ground connection, motorized mechanism, and control circuit.

• Ground connection is typically represented by a symbol resembling three horizontal lines connected to a point.

• Motorized circuit breaker includes a motorized mechanism for opening and closing the circuit.

• Control circuit is used to operate the motorized mechanism of the circuit breaker.

• Example: Ground symbol connected to the ground terminal, motori...read more

No, magnetic flow meters are not suitable for oil flow measurement due to the lack of conductivity in oil.

• Magnetic flow meters rely on the conductive properties of the fluid to measure flow rate

• Oil is not conductive enough for accurate measurement with a magnetic flow meter

• Alternative flow measurement technologies like ultrasonic or turbine meters are more suitable for oil flow measurement

No, I do not have a supervisor license.

• I do not possess a supervisor license at the moment.

• I have not pursued obtaining a supervisor license in my career.

• My focus has been on technical expertise rather than supervisory roles.

My process in chemical manufacturing involves designing, implementing, and optimizing production processes to ensure efficiency and quality.

• Designing chemical processes to meet production goals

• Implementing processes in the manufacturing plant

• Optimizing processes for efficiency and quality

• Monitoring and troubleshooting process issues

• Ensuring compliance with safety and environmental regulations

Transformer safety relays are devices used to protect transformers from faults and overloads.

• Transformer safety relays monitor the electrical parameters of a transformer, such as current, voltage, and temperature.

• They can trip the transformer offline in case of a fault to prevent damage.

• Some common types of transformer safety relays include overcurrent relays, differential relays, and temperature relays.
