Homework Help: Steady flow energy equation

  1. Feb 3, 2010 #1
    1. The problem statement, all variables and given/known data
    The power output of an adiabatic steam turbine is 5 MW and inlet and exit conditions are as under
    Given Inlet Pressure 2MPa Temprature 400 DEGREE CELSIUS Velocity 50m/s Elevation 10m
    Exit Pressure 15 KPa Temprature 0.9 dry Velocity 180m/s Elevation 6 m
    Determine the work done /kg of steam and the mass floe rate in kg/s

    2. Relevant equations
    Q-W=m(h2+v2^2/2+gZ2)-m(h1+v1^2/2+gz1) J/s
    3. The attempt at a solution

    I attempted to solve but can not under stand the meaning of .9 dry & how to find z1 and z2 pl. help
