A steam turbine has extractions to provide heating steam for the feedwater heaters in a power plant. The following parameters are known:

a. Isentropic Efficiency: .85

b. Inlet flow: 500 kg/s

c. Inlet pressure: 4500 kPa

d. Inlet Temperature: 330 C

e. Extraction 1: Pressure = 3300 kPa, flow rate=50 kg/s

f. Extraction 1: Pressure = 2200 kPa, flow rate=40 kg/s

g. Extraction 1: Pressure = 1600 kPa, flow rate=30 kg/s

h. Extraction 1: Pressure = 1200 kPa, flow rate=20 kg/s

i. Turbine Exhaust: Pressure=100 kPa

Determine the power, in MW, of the turbine.
