ME2320. Extra-credit III Extracredit (10 %) Group In-Class Assignment 1. Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 10 MPa, 450 o C, and 80 m/s, and the exit conditions are 10 kPa, 92 percent quality, and 50 m/s. The mass flow rate of steam is 12 kg/sec. Determine (a) the change in kinetic energy, (b) the power output, (c) the turbine inlet area, (d) the isentropic efficiency of the turbine,
