An adiabatic vortex tube, shown in the figure given below is supplied with 5 kg/s of air (inlet 1) at 500 kPa and 300 K. Two separate streams of air are leaving the device from outlets 2 and 3. Hot air leaves the device at a rate of 3 kg/s from outlet 2 at 100 kPa and 340 K, while 2 kg/s of cold air stream is leaving the device from outlet 3 at 100 kPa and 240 K. 

Consider constant specific heat of air is 1005J/kgK and gas constant is 287J/kgK. There is no work transfer across the boundary of this device. The rate of entropy generation is _____ kW/K (round off to one decimal place). 
    Correct answer is '2.238'. Can you explain this answer?
