Elemen tanah yang jenuh air dengan volume total V=1

Hubungan antara Berat Volume, Angka Pori, Kadar Air dan Berat Spesifik

AngkaPori (e)

ket :

V s = volume butiran

V v = volume pori

V w = volume air

Berat spesifik butiran padat ( GS)

ket :

w = berat volume air

s= berat volume butiran

Ws = berat butiran

Kadar Air (wc)
