Question 3
The volume flow rate of pump fed to a hydrocyclone was 129 L/min. Its solid content was held at
32% by volume. Samples of the feed, under flow and over flow streams were taken simultaneously,
dried and a size analysis carried out. The results obtained were:
Underflow rate = 30 L/min
Overflow rate = 99 L/min
