Aarvi Encon Interview Questions, Process, and Tips

The water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.

• The water cement ratio is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• The ideal water cement ratio varies depending on the type of concrete mix and desired strength.

• For example, a typical water cement ratio for a st

Minimum depth of foundation depends on various factors such as soil type, building load, and local building codes.

• Minimum depth of foundation is typically determined by the local building codes and regulations.

• Factors such as soil type, building load, and proximity to trees or other structures can also influence the minimum depth of foundation.

• For example, in areas with expansive clay soils, deeper foundations may be r

Concrete is a composite material made of cement, water, aggregates, and sometimes additives.

• Concrete is versatile and can be customized for different applications.

• There are different types of concrete based on strength, composition, and use, such as ready-mix, high-strength, and lightweight concrete.

• The most common type of concrete used in construction is Portland cement concrete.

• Special types of concrete include self-...read more

TDC stands for Top Dead Center and BDC stands for Bottom Dead Center. They are reference points in the rotation of an engine's crankshaft.

• TDC is the point where the piston is at its highest position in the cylinder during the compression stroke.

• BDC is the point where the piston is at its lowest position in the cylinder during the exhaust stroke.

• Understanding TDC and BDC is crucial for timing engine components such as v...read more

The clearance of TDC and BDC for a vertical reciprocating compressor can be measured using a dial indicator.

• Use a dial indicator to measure the distance between the top dead center (TDC) and bottom dead center (BDC) positions of the piston.

• Rotate the crankshaft to bring the piston to TDC and set the dial indicator to zero.

• Rotate the crankshaft to bring the piston to BDC and note the reading on the dial indicator.

• The di...read more

The clearance for big end bearing can be measured using a micrometer or a feeler gauge.

• Use a micrometer to measure the diameter of the crankshaft journal and the inner diameter of the big end bearing. The clearance is calculated by subtracting the crankshaft journal diameter from the bearing inner diameter.

• Alternatively, a feeler gauge can be used to measure the clearance by inserting the gauge between the crankshaft j...read more

Focus on proper alignment, tightness, material compatibility, and proper torque during suction and discharge valve box up.

• Ensure proper alignment of the valves to prevent leakage

• Check for tightness of the connections to avoid any leaks

• Use materials compatible with the fluid being handled to prevent corrosion or damage

• Apply the correct torque to the bolts to ensure a secure connection
