A piston/cylinder assembly contains 0.1 kg R-410A of quality x = 0.25 and at −20°C. The piston is initially free-floating. Stops are mounted so that the volume at the stops is three times greater... more

1) A constant volume process occurs in a closed container that has a volume of 4 m 3. Heat is added to the container such that the absolute pressure increases 120 kPa to 207 kPa. What is the work... more

An air-conditioning system involves the mixing of cold air and warm outdoor air before the mixture is routed to the conditioned room in steady operation. Cold air enters the mixing chamber at 7°C... more
