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 velovity. 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 of v(0)
a) in terms of the given parameters and any others that may be neededm how much work can be generated by the turbine? (friction can be neglected)?
b) if v(i) = 317m/s and v(0) = 126 m/s, what is the amount of work (in joules per mass of fluid) represented by the answer to (a)?
