Steam with specific enthalpy (h) 3214 k/kg enters an adiabatic turbine operating at steady state with a flow rate 10kg/s. As it expands, at a point where h is 2920 kJ/kg, 1.5 kg/s is extracted for heating expands to the turbine exit, where h = 2374 kJ/kg. Neglecting changes in kinetic and potential energies, the net power output (in kW) of the turbine is ___________
