In turbochargers a turbine is directly connected to a compressor. The power harvested by the turbine is used to power the compressor. In the figure below a turbine runs on steam and powers a compressor on air. Air can be considered a perfect gas with k = 1.34, R = 0.28 kJ/kgk and cp = 1.02 kJ/kgK. The air enters the compressor at p₁ 1bar, T₁ = 300K and a mass flow 5.9 kg/s and exits at p2 = 5.2 bars. The steam enters the isentropic turbine at P3 = 2 MPa, T3 = 320°C and exits at p4 = 100 kPa. rate of mdot = State 2 Isentropic Compressor State 1 Air - perfect gas T₁ = 300K P₁= 1 bar W Answer: tubine State 4 Isentropic Turbine State 3 Steam T3=320°C P3= 2MPa What is the enthalpy at state 2? Please enter your answer in kJ/kg
