Day Six

Dear Professor Chan,

I found the Andreasen apparatus part of today’s lecture a little difficult to understand. Could you please help me with a few questions?

1. I just wanted to confirm that the purpose of the apparatus is to measure particle size
2. What is the purpose of evaporating the samples after they’ve been collected?
3. Samples are drawn every 10 minutes. When do we stop taking samples?
4. How are the larger particles that have settled to the bottom measured?

Thank you!

Annie Dou

I missed the next PPF lecture because I called Jez in the morning.

Here's Kim Chan's reply.

I’ve addressed your questions in the lecture this morning, were you there?

Pwnd.
