An adiabatic turbine has steam flowing steadily through it. The inlet conditions of the steam are P1=6 MPa, T1= 400C and v1=80 m/s, while the exit conditions are P2= 40kPa, .9 quality x=.9, and v0= 50 m/s. The mass flow rate of the steam is m= 20kg/s. Determine the change in kinetic energy, b the power output, and c the turbine inlet area.
Calculate the change in free-energy associated with the formation of a critical spherical nucleus in pure liquid nickel that is 200 ºC under cooled. Properties of Nickel: Heat of Fusion 2660 J/cm3; Surface Energy 255x10-7 J/cm2 ; Freezing Temperatur..
