Two gas storage tanks are interconnected through an isothermal expander. tank 1 (v = 1) is initially at 298 k and 30 bar. tank 2 (v = 1) is initially at 298 k and 1 bar. reversible heat transfer is provided between the tanks, the expander, and the surroundings at 298 k. what is the maximum work that can be obtained from the expander when isothermal flow occurs from tank 1 to tank 2?

The center of a long frictionless rod is pivoted at the origin, and the rod is forced to rotate in a vertical plane with constant angular velocity \omega. write down the lagrangian for a bead of mass m threaded on the rod, using r as your generalized coordinate, where r, \phi are the polar coordinates of the bead. (notice that \phi is not an independent variable since it is fixed by the rotation of the rod tobe \phi = \omega * t) solve lagrange's equation for r(t). what happens if the bead is initially at rest at the origin? if it is released from any point ro > 0, show that r(t) eventually grows exponentially. explain your results in terms of the centrifugal force m* \omega ^2 *r.
