L&T Construction Project Engineer Interview Questions, Process, and Tips

Bulk modulus is a measure of a material's resistance to compression under pressure.

• It is a measure of a material's compressibility

• It is defined as the ratio of change in pressure to the fractional volume compression

• It is used in the study of elasticity and fluid mechanics

• Examples of materials with high bulk modulus include diamond and steel

• Examples of materials with low bulk modulus include rubber and foam

G constant is required during sand bulking to account for the change in volume due to the presence of air voids.

• G constant is used to calculate the volume of sand when it is in a loose state.

• The presence of air voids in sand causes it to increase in volume, which is known as bulking.

• The amount of bulking depends on the moisture content and the type of sand.

• G constant is determined experimentally by comparing the volume...read more

The outer diameter of HDPE pipe varies based on the intended use and specifications.

• HDPE pipes are available in a range of sizes from 16mm to 2000mm.

• The outer diameter of HDPE pipe is typically larger than the inner diameter.

• The thickness of the pipe wall also varies based on the intended use and pressure requirements.

• HDPE pipes are commonly used for water supply, gas distribution, and sewage systems.
