A cylindrical surface with radius R, such that in equilibrium, the rod is horizontal with its center of mass on top of the cylinder. The rocking of the rod on the surface is characterized by the angle Î¸, as shown in Fig. (a) Determine the position of the center of mass Rcm(), relative to the origin set at the top of the cylinder at the point of its contact with the rod when Î¸=0. (b) Using (a), find the gravitational potential energy of the rod U(Î¸), show that Î¸=0 is an equilibrium position, and determine whether this equilibrium is stable.

(6) A project requires a steam nozzle capable of delivering 1 kg/s of saturated vapor at 100 kPa. The plant steam supply provides an endless supply of steam at 200°C, pressurized to 10 bar. Given a feed velocity of 100 m/s what will the exit velocity be? What is the required cross- sectional area? Assume no work is being done on the nozzle. (5 points) (7) Consider the mixing of 0.8 kg/s of hot water at 348 K and 1 kg/s of cool water at 298 K that is generating warm water. Assume no work is being done and the system is in steady state, but heat is lost at the rate of 30 kJ/s during this mixing. Find the temperature of the warm water flow stream? Assume $C_p$ =4.18 kJkg$^{-1}$K$^{-1}$ (5 points)
