Repeat Problem 2.10 with the following values: G_s = 2.7, temperature of water = 23°C, t = 120 min, and R = 25.

Data From Problem 2.10

A hydrometer test has the following results: G_s = 2.6, temperature of water = 24°C, and R = 43 at 60 minutes after the start of sedimentation (see Figure 2.30). What is the diameter D of the smallest-size particles that have settled beyond the zone of measurement at that time (that is, t = 60 min)?
