Consider the axial laminar flow between two parallel porous plates separated by a distance 2W. There is a transverse velocity yw into the channel through the top plate and out through the bottom plate at the same value. Develop an expression for the axial velocity profile u( y) for fully developed flow

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
