A certain power plant produces a net power output of 120 MW. The constant pressure condenser operates at 8 kPa and the constant pressure boiler operates at 1 MPa. The steam enters the turbine, which operates at 88% efficiency at 600°C, and the water leaving the condenser at 8kPa enters the 72% efficient pump.

Find:

a) mass flow rate in kg/hr of the working fluid,

b) heat suplied to the boiler in kJ/hr,

c) heat rejected to the condenser in kJ/hr;

I want a personalized answer so please do not copy from other's work. I need it ASAP

Steam properties
At 1 Mpa and 600°C:
At 8 kPa:
h = 3697.9 kJ/kg
s = 8.029 kJ/kg-k
h = 173.88 kJ/kg
hg = 2577 kJ/kg
St=0.5926 kJ/kg-K
Sig = 8.2277 kJ/kg-K
V₁ = 0.0010084 m³/kg
