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, 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_0
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 = 317m/s and v_0 = 126m/s, what is the amount of work (in joules per mass of fluid) represented by the answer to (a)?
