Homework Statement
Verbatim from the problem:
"About [tex]10000km^3[/tex] of water is held behind dams in reservoirs around the world.Most reservoirs are at mid-latitudes, whilst the bulk of the world’s oceans are concentrated near the equator. By using conservation of angular momentum, estimate by how much the overall movement of water into reservoirs has changed the length of the day."
Homework Equations
[tex]r^{2}_{g} = \frac{I}{M}[/tex]
[tex]\rho_E = \frac{M}{V}[/tex]
[tex]V = \frac{4}{3} \pi R^{3}_{E}[/tex]
[tex]L = I\omega = r^{2}_{g} M\omega[\tex]
