## Properties of Fluids- Density or Mass density, Specific weight, Specific Volume, Specific Gravity, Surface Tension

1.. Density or Mass density(ρ) : The density of a fluid is defined as the ratio of the mass of the fluid to its volume of fluid. Density is a crucial property that defines how much mass is packed into a given volume of a substance. It is expressed as the...

## Lacey’s Silt Theory of Canals

Lacey’s Silt Theory of Canals According to what I know, Lacey’s silt theory is a method for designing irrigation canals that considers the interaction between water flow and sediment transport. It was developed by G. Lacey in the early 20th century. Lacey’s silt theory is based on the idea that...

## Kennedy’s Silt Theory

Kennedy’s Silt Theory According to what I know, Kennedy’s Silt Theory states that the vertical eddies rising from the bed of an alluvial channel are responsible for keeping silt particles in suspension. The theory defines a critical velocity that will prevent silting or scouring. Kennedy’s equation relates the critical velocity to the...

## Relation Between Duty, Delta, and Base Period

Relation Between Duty, Delta, and Base Period To understand the relation between duty, delta, and base period in the context of irrigation engineering, we can break it down step by step: The relationship between duty (D), delta (Δ), and base period (B) can be expressed as follows: If field area...

## Types of Shear Failures in Soils

Types of Shear Failures in Soils Shear Failures in Soils are categorized into three primary classes: general shear failure, local shear failure, and punching shear failure. Thanks for Visiting 🙂

## Field Tests on Sand

Field Test on Sand When conducting a field test on sand, there are several aspects to consider, including its composition, behavior under different conditions, and potential applications. Field tests on sand are crucial in various industries such as construction, geotechnical engineering, environmental science, and agriculture. These tests help in understanding...

## Short note on Strip footing

Strip Footing A strip footing, also known as a continuous footing, is a type of shallow foundation used to support a load-bearing wall or a line of columns. It is a long strip of concrete that extends the entire length of the wall and spreads the load over a larger...

## Importance of NDT tests on concrete?

Introduction Non-destructive testing (NDT) is a crucial process in the construction and maintenance of concrete structures. It helps to evaluate the integrity and performance of the concrete without causing any damage to the structure. This essay discusses the importance of NDT tests on concrete and how these tests contribute to...

## Define Water-Cement (w/c) Ratio and effects of water-cement ratio?

Water-Cement Ratio The water-cement ratio is a crucial parameter in the concrete industry, as it directly affects the properties of the final product. A lower water-cement ratio results in a denser, stronger, and more durable concrete, while a higher ratio leads to a more porous, weaker, and less durable concrete....

## Tests on Cement

Cement Testing: An OverviewCement is a vital construction material used worldwide in various applications, such as concrete production, mortar, and grout. The quality and performance of cement are crucial for the success of construction projects. To ensure the cement meets the desired standards and specifications, several tests are conducted. In...

## Types of Cement and their properties

Types of Cement Cement is a crucial building material used in construction for binding materials together. There are various types of cement, each with its own unique properties and applications. The most common types of cement include: 1. Ordinary Portland Cement (OPC): This is the most widely used type of...

## Strap footing

Strap Footing A strap footing, also known as a combined footing, is a type of foundation that is used to support two or more columns in close proximity to each other. It is designed to distribute the load from the supported columns over a wider area of soil to prevent...

## Mat/Raft foundation

A raft foundation, also known as a mat foundation, is a type of foundation that is used to distribute the load of a structure over a large area. It is commonly used when the soil has low bearing capacity or when the loads from the structure are expected to be...

## Young’s Modulus and it’s applications with Example

Young’s Modulus Young’s modulus, also known as the elastic modulus, is a measure of the stiffness of a material. It quantifies the relationship between stress (force per unit area) and strain (proportional deformation) in a material undergoing tension or compression. The modulus is named after Thomas Young, a 19th-century British...
