A speculator is considering the purchase of a commodity that he reckons has a 60% of increasing in value over the next month. If he purchases the commodity and it does increase in value, the speculator will make a profit of $200000 otherwise he wi
Show that a steady solution of the full Navier-Stokes euqations of the form u=u(theta)(r,z)e(theta) is not possible, so that any rotary motion u(theta)(r,z) in this system must be accompanied by a secondary flow (ur, uz does not equal 0).
