    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)
