Results
After conducting the cow faecal sieving process, we obtained the following results:
Sieve Sizes
The cow faecal samples were sieved using three different sieve sizes:
- Coarse Sieve (4 mm): This sieve size allowed larger particles to pass through, retaining only the smaller particles.
- Medium Sieve (2 mm): This sieve size retained particles of medium size, excluding both larger and smaller particles.
- Fine Sieve (1 mm): This sieve size retained only the finest particles, excluding larger particles.
Particle Distribution
After sieving, the cow faecal particles were categorized into three groups based on their size:
- Coarse Particles: Particles that passed through the coarse sieve (4 mm) but were retained in the medium sieve (2 mm).
- Medium Particles: Particles that passed through the medium sieve (2 mm) but were retained in the fine sieve (1 mm).
- Fine Particles: Particles that passed through the fine sieve (1 mm) and were collected.
We measured the weight and volume of each particle group to determine the distribution of cow faecal particles across different sizes.
Based on the results, we found that the majority of the cow faecal particles were classified as fine particles, followed by medium particles and coarse particles. This indicates that the cow faecal material consists mostly of smaller particles, with a smaller proportion of larger particles.
These results provide valuable insights into the size distribution of cow faecal particles and can be used for further analysis and research in the field of agricultural waste management.
