Problem 3
In class, we solved for the vorticity distribution for a "real" line vortex diffusing in a viscous fluid.
Integrate this vorticity distribution to find the tangential velocity as a function of radius. Plot the
velocity distributions for a a line vortex of circulation 0.5 mls in 20 °C air for times of 1, 10, and 100
seconds.
13. Find an equation of the sphere with center (-3, 2, 5) and radius 4. What is the intersection of this sphere with the yz-plane?
A 200 gallon tank initially contains 100 gallons of water with 20 pounds of salt. A salt solution with 1/5
pound of salt per gallon is added to the tank at 10 gal/min, and the resulting mixture is drained out at 5
gal/min. Let Q(t) denote the quantity (lbs) of salt at time t (min).
(a) Write a differential equation for Q(t) which is valid up until the point at which the tank overflows.
Q' (t) =
=
(b) Find the quantity of salt in the tank as it's about to overflow.
