Awell-insulated diffuser is supplied with carbon dioxide at 110 kpa, 300 k, and 300 m/s. it is claimed that this diffuser will deliver the gas at 240 kpa and 52 m/s. assuming variable specific heats, determine: (a) the diffuser exit temperature (k) (b) if the process is reversible, irreversible, or impossible. (c) if irreversible, the entropy generation rate for the gas (kj/kg. k).

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
