A turbine operates by the impact of a high-velocity jet of steam against the turbine blades. The steam leaves the turbine at a lower velocity. For the turbine depicted below, steam from a high-pressure nozzle enters the air and strikes the blades of a turbine at an average velocity of v_i and leaves the turbine at an average velocity v_o.

a. In terms of the given parameters and any others that may be needed, how much work can be generated by the turbine? (Friction can be neglected.)
b. If v_i = 317 m/s and v_o = 126 m/s, what is the amount of work (in Joules per mass of fluid) represented by the answer to (a)?
