Week 2: Classification of clastic sediments, fluid flow
Upon completion of this unit students should be able to:
- Classify clastic sediments and sedimentary rocks based on grain size
- Discuss fluid density, fluid viscosity and their effects on grain transport
- Distinguish between dynamic viscosity and kinematic viscosity
- Define laminar and turbulent flow using the Reynolds equation
- Explain particle entrainment, including relevant forces that act on a particle
- Use the Hjulstrom curve to distinguish between erosion and deposition for particular grain sizes
- Give a conceptual explanation of Stoke's law

The second reading assignment is for week 2, and will be due Wednesday February 6.
Lab week 2:
In lab this week we will look at grain size in clastic sedimentary rocks. I will split the lab into two groups, and you will take turns running the rotap sieve shaker and making a grain size key.
