Water at high pressure and properties p1, v1, u1, hi and mass m1 is in a container and part of the water with mass me and properties pe, ve, ue, he exits the container after "pushing" a turbine. eventually, the pressure drops and the process stops. at the end of the process, the water in the container has properties p2, v2, u2, h2. if no heat crossed the boundaries of the container, what is the total work w done by the water to power the turbine?
