Recitation 11 Problem 1 400 kg/min of steam enters a steam turbine at 300 °C and 80 bar through a 8.5-cm diameter line and exits at 100 °C and 10.0 bar through a 5.5-cm line. The exiting stream may be vapor, liquid, or "wet steam", a mist composed of saturated water vapor and entrained liquid droplets. Find how much power W (kW) is transferred from the turbine to the steam? The answer can be positive or negative. Neglect AE, but not AEK. What percentage (%) of the total power is due to kinetic energy changes?
