Superheated R134a enters a superb turbine at 320 kPa and 120 Celsius and exits the turbine at 67.5 Celsius and 60 kPa. An identical stream of superheated R134a enters a decent turbine at 320 kPa and 120 Celsius and exits the turbine at 60 kPa and 70 Celsius. How much extra power, in units of percent, can the superb turbine generated when compared with the power output from the decent turbine

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
