Answer #1

Question 1: Hydraulic conductivity through soils (or permeability ) can be measured in the laboratory using either constant or falling head conditions.

Because permeability can be determined in the laboratory by direct measurements using permeameters by allowing water to flow through soil either under constant or falling head .

Question 2:

False, because the flow of water is different through different soils i.e., the head will be different for differnt types of soils.

Question 3: ASTM Stands for American society for testing amd materials
