The mass flow rate into a steam turbine is 1.5 kg/s, and the heat transfer from the turbine is 8.5 kW. The following data are known for the steam entering (i) and leaving (e) the turbine:

P_i = 2.0 MPa
T_i = 350C
V_i = 50 m/s
z_i = 6 m

P_e = 0.1 MPa
x_e = 100%
V_e = 200 m/s
z_e = 3 m (above the reference elevation with g = 9.8066 m/s^2)

Determine the power output of the turbine.
