(a) On a temperature versus entropy (Ts) diagram, does the actual exit state of an adiabatic turbine has to be on right-hand side or left-hand side of its isentropic exit state? Why? ( 3 marks) (b) Helium gas is compressed from 90kPa and 30C to 450kPa in a reversible-adiabatic process. Determine the final temperature and the work done, assume that the process take place in; (i) a piston cylinder device, and (ii) a steady flow compressor
