Abstract:
The expression "capillary tension" is used as a name for the negative pressure existing in the water in unsaturated soil and porous cell-vacuum gauge instruments used in its measurement are called tensiometers. Principles underlying the use of indicating, recording, and differential tensiometers are discussed and apparatus used by the authors is described.
