1.superheated water vapour at 1.4MPa &250degree C is allowed 2 cool at const vol.until the temp. drops to 150 degree C.at the final state determine
1.the pressure
2.quality
3.enthalpy
2.a piston cylinder device contains 0.8kg of steam at 300 degree C &1MPa.steam is cooled at const pressure until one half of the mass condenses.
1.find the final temp.
2.determine the vol. change
