LAMPIRAN 2 DATA-DATA HASIL PENGUKURAN DENSITAS

1. True density

Mengukur True density dengan menggunakan rumus:

Keterangan :

ρs = True Density sampel (g/cm3)

m1 = Massa picnometer kosong (g)

m2 = Massa picnometer diisi media cair (g)

m3 = Massa picnometer diisi serbuk sampel (g)

m4 = Massa picnometer diisi serbuk sampel dan media cair (g)

ρmedia cair = Densitas media cair (g/cm3)

1.1 True density eksperimen

1. True Density NdFeB Flakes

(5)

2. True Density MQP – B+

3. True Density MQA

(6)

2.Bulk density

Mengukur Bulk density dengan menggunakan rumus:

ρ = x ρCairan

Keterangan :

ρ = Bulk Density sampel (g/cm3)

mk = Massa kering sampel (g)

mb = Massa basah sampel (g)

ρmedia cair = Densitas media cair (g/cm3)

2.1 Bulk density eksperimen
