Webpermeability test uses a permeameter with piezometer attached to its sides. The graduated cylinder collects 800 cu. of water in 100 seconds. The diameter of the soil sample is 18 cm. Elevation of the water in the upper piezometer is 180 cm. and that of the lower piezometer is 116cm. The piezometer tips are spaced 20 cm. on center. Web5.2 THE COEFFICIENT OF PERMEABILITY Typical values of k for various types of soil are shown in Table 5.1. This table illustrates the enormous range of values of permeability for soils.
