Hydraulic refers to the study of fluids in motion and the engineering applications of fluid mechanics.

• Hydraulic engineering involves the design and construction of structures that control the flow and pressure of liquids, such as dams, canals, and pipelines.

• Hydraulic systems use fluid pressure to generate, control, and transmit power, commonly found in machinery like hydraulic lifts and brakes.

• Hydraulic principles are ...read more

MDD of GSB stands for Maximum Dry Density of Granular Sub Base, which is a key parameter in civil engineering for road construction.

• MDD is the maximum density that can be achieved for a particular granular material under specific compaction conditions.

• It is typically measured in the laboratory using a standard compaction test such as Proctor compaction test.

• The MDD value helps in determining the optimum moisture conten...read more

The carriage way width of a four-lane road is typically around 7 meters.

• Carriage way width is the total width of the road available for vehicles to travel in one direction.

• For a four-lane road, the carriage way width is usually divided equally among the lanes.

• In this case, each lane would have a width of approximately 1.75 meters.

• The total width of the road including all lanes and any additional features like shoulders

Carpet area of a building can be calculated by measuring the inner dimensions of the building excluding the walls.

• Measure the length and width of each room in the building

• Exclude the thickness of walls from the measurements

• Calculate the area of each room by multiplying length and width

• Sum up the areas of all rooms to get the total carpet area of the building
