A tank whose volume is unknown is divided into two parts by a partition. One side of the tank contains 0.03 m³ of refrigerant-134a that is a saturated liquid at 0.9 MPa, while the other side is evacuated. The partition is now removed, and the refrigerant fills the entire tank. If the final state of the refrigerant is 20°C and 280 kPa, determine the volume of the tank.

Refrigerant-134a is in an insulated canister with temperature 25 C. There is a partition in the canister so the refrigerant is a saturated liquid and takes up 1/100 of the volume of the canister. The rest of the volume is evacuated. When the canister is activated by squeezing (no work done activating) the partition breaks and the refrigerant fills the total volume. Final pressure is 100 kPa. a.) What are two assumptions needed for the problem? What properties are needed to solve part b.) and c.) b.) What is the change in specific enthalpy within the canister? c.) What is the final quality of the refrigerant within the canister?

Required information Problem 08.036E - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS - Refrigerant Constant Volume System NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A 17-ft3 rigid tank contains refrigerant-134a at 30 psia and 55 percent quality. Heat is transferred now to the refrigerant from a source at 120°F until the pressure rises to 50 psia. Assume the surroundings to be at 75°F. Problem 08.036E.b - Exergy Destroyed for Refrigerant Constant Volume System Determine the exergy destroyed during this process. The exergy destroyed during this process is Btu.

Ex: Argon in the amount of 1.5 kg fills a 0.04-m³ piston- cylinder device at 550 kPa. The piston is now moved by changing the weights until the volume is twice its original size. During this process, argon's temperature is maintained constant. Determine the final pressure in the device.
