Water vapor enters a turbine operating at steady state at 480°C, 90 bar, with a velocity of 300 m/s, and expands adiabatically to the exit, where it is saturated vapor at 12 bar, with a velocity of 145 m/s. The exit diameter is 0.35 m. Determine the power developed by the turbine, in kW.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
