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
2. True Density MQP – B+
3. True Density MQA
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
No SAMPEL
