Chapter 5, Problem 5.61P

An insulated, rigid tank is divided into two equal parts by a membrane. (Figure 1) At the beginning, one part contains 9 kg of nitrogen at 500 kPa and 50 °C, while the other part is completely evacuated. The membrane is punctured and the Part A gas expands into the entire tank. Use the PG model. Determine the final temperature (T3). Express your answer to the nearest integer. HA Value Units Submit Request Answer Part B Determine the final pressure (p2 ). Express your answer to the nearest integer. ΑΣφ vec kPa Submit Request Answer

4- A tank contains dry air at 1.03 bar and 21. A Flask of dry air containing 0.9 kg of air at 10.3 bar and 24 °C is connected to the tank by a negligible volume. Finally, the pressure is 2.06 bar and the temperature is 22 °C. What is the volume of the tank? (R=287 J/kg K)

2. Saturated steam at 100°C is heated to 350°C at constant pressure. Use the steam tables to determine: a. The pressure in bar. b. the required heat input (J/s) if a continuous stream flowing at 100 kg/s undergoes the process.
