A turbine operates by the impact of a high velocity jet of steam at atmospheric pressure against the turbine blades. The steam leaves the turbine at a lower velocity. If the entry velocity to turbine is V1= 317m/s, and the exit velocity from turbine is V2=126m/s, find the amount of work in Joules /Kg performed by the turbine. List all assumptions. Hint: This process all takes place at atmospheric pressure
