Aarvee Associates Interview Questions, Process, and Tips

Water content and specific gravity are important parameters in soil analysis.

• Water content refers to the amount of water present in soil, expressed as a percentage of the soil's total weight.

• Specific gravity is the ratio of the density of a substance to the density of a reference substance (usually water) at a specific temperature.

• Water content affects the soil's physical properties, such as its ability to retain moist...read more

Soil degradation refers to the decline in soil quality and fertility due to various factors.

• It is caused by factors such as erosion, deforestation, overuse of chemical fertilizers, and pollution.

• Soil degradation leads to reduced agricultural productivity, loss of biodiversity, and increased vulnerability to droughts and floods.

• Examples of soil degradation include desertification in arid regions, soil erosion from inten...read more

A borehole is a narrow, deep hole drilled into the ground to extract water, oil, gas, or minerals.

• Boreholes are commonly used for water supply in areas where surface water is scarce.

• They can also be used for geothermal energy extraction.

• Boreholes are typically drilled using specialized equipment, such as rotary drilling rigs.

• The depth of a borehole can vary depending on its purpose, ranging from a few meters to several...read more

Liquid limit and plastic limit are soil properties used to determine the behavior of soil under different moisture conditions.

• Liquid limit is the moisture content at which a soil transitions from a liquid to a plastic state.

• Plastic limit is the moisture content at which a soil transitions from a plastic to a semi-solid state.

• These limits are determined through laboratory tests using specific apparatus and procedures.

• Th...read more

The number of segments in one ring depends on the design and specifications of the tunnel project.

• Number of segments can vary based on tunnel diameter

• Segments are typically made of concrete or other durable materials

• Segments are used to form the tunnel lining for structural support

• Example: A tunnel with a diameter of 10 meters may have 6 segments per ring

Conductors are selected based on factors like material, size, insulation, and current carrying capacity.

• Consider the material of the conductor (e.g. copper, aluminum)

• Determine the size of the conductor based on the current it will carry

• Choose the appropriate insulation for the conductor based on the environment it will be used in

• Ensure the conductor has the required current carrying capacity for the application
