Problem 03.030 - Piston-cylinder device NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A piston-cylinder device contains 0.84 kg of refrigerant-134a at -10C. The piston that is free to move has a mass of 12 kg and a diameter of 25 cm. The local atmospheric pressure is 88 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 15C. Use data from the tables. R-134 -10C Problem 03.030.a - Final pressure of refrigerant Determine the final pressure of the refrigerant-134a. The final pressure is kPa.
