In a steam turbine, water vapor enters at a temperature of 450C and a pressure of 2.5 MPa, at a speed of 60 m/s at a height of 12 m, and at a pressure of 20 kPa at a speed of 0.85 degrees of dryness, at a speed of 180 M/s at a height of 6 m. During this process, a power generation of 5 MW occurs. According to the given; a) compare kinetic, potential and enthalpy changes. b) calculate the work done by the unit mass of steam flowing from the turbine. c) calculate the mass flow of steam.
