Stress Isobars are-

Detailed Solution: Question 20

An isobar or pressure bulb is a stress contour or a line that connects all points below the ground surface at which the vertical pressure is the same.

An isobar is a curved spatial surface and resembles a bulb in shape because the vertical pressure at all points in a horizontal plane at equal radial distances from the load is the same.

The ozonation in drinking water helps to remove

Detailed Solution: Question 23

Because of its excellent disinfection and oxidation qualities, ozone is widely used for drinking water treatment. Ozone can be added at several points throughout the treatment system, such as during pre-oxidation, intermediate oxidation, or final disinfection. Usually, it is recommended to use ozone for pre-oxidation before a sand filter or an active carbon filter (GAC). After ozonization, these filters can remove the remaining organic matter (important for final disinfection).
