Standard Penetration Test | How to Test your Soil | SPT of Soil
The sampler consists of two halves that can capture a soil sample as it's driven into the ground. Step 3: Hammering. A standard weight (usually 63.5 kg) hammer is raised to a specific height and released, striking the anvil on top of the drill rod. This impact drives the split-spoon sampler into the soil.
Fans, Blowers and Compressors
Types of Blowers. Centrifugal Blower: Centrifugal blowers, also known as centrifugal fans, use an impeller with backward-curved, forward-curved, or radial blades to create a centrifugal force that accelerates the air or gas outward. Blowers are utilized in HVAC systems, industrial ventilation, and air pollution control for moderate to high …

2.4: Soil Mechanical Parameters
2.4.2. Atterberg Limits. The Atterberg limits are a basic measure of the nature of a fine-grained soil.Depending on the water content of the soil, it may appear in four states: solid, semi-solid, plastic and liquid. In each state the consistency and behavior of a soil is different and thus so are its engineering properties.
