Density of bentonite and prestressing formula are two separate topics in civil engineering.

• Density of bentonite is typically around 2.0-2.5 g/cm^3.

• Prestressing formula involves calculating the stress in a structure due to applied loads and prestressing forces.

• Example of prestressing formula: Stress = Load / Area + Prestressing Force / Area

CoS billing procedure involves categorizing and prioritizing traffic for billing purposes.

• CoS (Class of Service) is a method used in networking to prioritize different types of traffic.

• Billing procedures based on CoS involve assigning costs or charges to different classes of service.

• Examples include charging more for high-priority traffic like VoIP calls compared to lower-priority data traffic.

Bentonite is used as a drilling fluid to stabilize boreholes before pulsing.

• Bentonite is mixed with water to form a slurry and pumped into the borehole.

• The slurry fills the borehole and stabilizes the walls, preventing collapse.

• After the bentonite has set, pulsing can be done without the risk of borehole collapse.

• Pulsing is a technique used in geophysical exploration to measure the properties of the subsurface.
