2. A mass of 10kg of water is stirred by a mixer for one hour.
During this time the temperature
increased by 1 degree C. What is the power output of the mixer in
watts? What is the size of the
smallest eddies during the mixing. Hint: We briefly covered the
Kolmogorov length-scales in
class, the needed equation in terms of energy dissipation (power
per mass) and viscosity can be
found here:
