Laminar flow is a smooth, orderly flow of fluid while turbulent flow is a chaotic, irregular flow.

• Laminar flow occurs at low velocities and is characterized by layers of fluid moving parallel to each other.

• Turbulent flow occurs at high velocities and is characterized by eddies and swirls in the fluid.

• Laminar flow is commonly observed in blood vessels while turbulent flow is observed in rivers and oceans.

• The transition ...read more

Quicksand is a condition where loose sand becomes saturated with water, causing it to behave like a liquid.

• Quicksand is formed when water saturates loose sand, reducing friction between sand particles.

• It can be found near riverbanks, marshes, or coastal areas.

• When a person or object steps on quicksand, they sink slowly due to the lack of support from the liquid-like sand.

• To rectify quicksand condition, one should avoid...read more

To determine under and over reinforced sections in RCC, analyze the stress-strain behavior of the concrete and steel reinforcement.

• Calculate the moment of resistance using the stress-strain relationship of concrete and steel.

• Compare the calculated moment of resistance with the applied moment to identify under or over reinforced sections.

• Under reinforced sections have a lower moment of resistance than the applied moment...read more

The sequence of removing formwork in a construction site is a logical process that involves several steps.

• Inspect the concrete for sufficient strength and curing

• Remove any bracing or supports

• Remove the formwork in a systematic manner, starting from the top and working downwards

• Ensure proper coordination with other trades and activities on the site

• Inspect the removed formwork for any damages or defects

• Dispose of the for

Honey combing is a term used in construction to describe a defect in concrete where voids or gaps are left in the structure.

• Honey combing occurs when the concrete mix is not properly compacted, resulting in air pockets and voids.

• It weakens the structure and reduces its durability.

• To rectify honey combing on site, the following steps can be taken:

• - Remove loose or weak concrete from the affected area.

• - Clean the surface...read more
