Rashmi Group Junior Engineer Interview Questions and Answers

Density of slurry is the mass of the slurry per unit volume.

• Density of slurry is typically measured in kg/m^3 or lb/ft^3.

• It is calculated by dividing the mass of the slurry by its volume.

• The density of slurry can vary depending on the concentration of solids in the liquid.

• For example, a slurry with a high concentration of solids will have a higher density.

SPL stands for Sound Pressure Level and SEL stands for Sound Exposure Level.

• SPL is a measure of sound intensity relative to a reference level.

• SEL is a measure of sound exposure over a period of time, typically in decibels.

• Both SPL and SEL are commonly used in the field of acoustics and noise control.

The red area typically refers to a section or region that is highlighted or marked in the color red.

• Red area can indicate danger or warning.

• In engineering, red areas on diagrams or blueprints may signify areas of high risk or critical components.

• Examples: red area on a map indicating a fire hazard zone, red area on a circuit diagram highlighting a high voltage section.

Boiler maintenance and bowl mill are crucial for the efficient functioning of a thermal power plant.

• Boiler maintenance involves regular cleaning, inspection, and repair of the boiler to ensure its safe and efficient operation.

• Bowl mill is a type of grinding mill used in power plants to grind coal and convert it into a powder form that can be burned more efficiently.

• Regular maintenance of bowl mills is necessary to ensu...read more

Evaporation system is a process of converting liquid into vapor by heating or reducing pressure.

• Evaporation system is used in various industries like food, chemical, and pharmaceuticals.

• It is used for concentration of solutions, separation of volatile components, and purification of liquids.

• Examples of evaporation systems include rotary evaporators, falling film evaporators, and flash evaporators.

Heat transfer is the movement of thermal energy from one object to another, while mass transfer is the movement of mass from one place to another.

• Heat transfer involves the transfer of thermal energy due to a temperature difference, while mass transfer involves the transfer of mass due to a concentration difference.

• Heat transfer can occur through conduction, convection, or radiation, while mass transfer can occur throu...read more
