Question: sand and other granular materials appear to flow that is...

Question details

Sand, and other granular materials appear to flow; that is, you can pour them from a container or a hopper. There are whole textbooks on the transport of granulair materials. Therefore, is sand a fluid? Explain. 4. 5. Over the last 100 years, it is estimated that the top 700 m of the ocean have been heated by 0.1 degrees Celsius. Using the thermal expansivity of water, estimate how much sea-level rise this estimate implies. How much sea-level rise would a 1 degree Celsius heating of the top 700 m imply? For flowing water, what is the magnitude of the velocity gradient needed to produce a shear stress O 6.
