To calculate bulk density of leaves straw, bajara husk, sawdust.
Material: leaves straw, bajara husk, sawdust, known volume beaker (250 ml), weighning balance.
Procedure:
- Take a known volume beakers and add all three samples in three different beakers.
- Tapped the samples thrice with rod then compaction is done through this.
- Then remove the sample from beaker and weigh it.
Formula:
Bulk Density (g/cc) = weight of sample / Total volume
Calculation:
1.Bajara Husk:
Bulk Density (g/cc) = weight of sample / Total volume
= 41/250
=0.16 g/cc
2. Leaves Straw:
Bulk Density (g/cc) = weight of sample / Total volume
= 65/250
=0.26 g/cc
3. Sawdust:
Bulk Density (g/cc) = weight of sample / Total volume
= 78/250
=0.31 g/cc
Result: The bajara has low bulk density so it has more void spaces and high water holding capacity.
