An insulated, rigid tank whose volume is 0.5 m³ is connected by a valve to a large vessel holding steam at 40 bar, 480°C. The tank is initially evacuated. The valve is opened only as long as required to fill the tank with steam to a pressure of 20 bar. Determine: (a) the final temperature of the steam in the tank, in °C, the final mass of the steam in the tank, in kg, and (b) the amount of entropy produced, in kJ/K. Part A Your answer is correct. Determine the final temperature of the steam in the tank, in °C, and the final mass of the steam in the tank, in kg. T₂ 660.25 °℃ 2.338 m₂ = kg

### Thermodynamic Problem Solving: Insulated Tank with Steam #### Problem Statement An insulated, rigid tank whose volume is \(0.5 \, \text{m}^3\) is connected by a valve to a large vessel holding steam at \(40 \, \text{bar}\), \(480°C\). The tank is initially evacuated. The valve is opened only as long as required to fill the tank with steam to a pressure of \(20 \, \text{bar}\). Determine: - (a) The final temperature of the steam in the tank, in °C, and the final mass of the steam in the tank, in kg. - (b) The amount of entropy produced, in kJ/K. #### Part A **Determine the final temperature of the steam in the tank, \( T_2 \), and the final mass of the steam in the tank, \( m_2 \):** - **\( T_2 \)**: \( 660.26 \, \degree \text{C} \) - **\( m_2 \)**: \( 2.338 \, \text{kg} \) #### Part B **Determine the amount of entropy produced, \( \Delta S_{gen} \), in kJ/K:** Input area is shown for data entry: - **\( \Delta S_{gen} \)**: ________ \( \text{kJ/K} \) (Submit Answer button shown for calculation verification) #### Explanation In Part A, the user correctly determined the final temperature of the steam as \(660.26 \, \degree \text{C}\) and the final mass of steam as \(2.338 \, \text{kg}\) based on the provided thermodynamic parameters and constraints. In Part B, the process of determining the entropy change is initiated but the result has not yet been provided or confirmed. This example illustrates the problem-solving approach to understanding the behavior of steam under specific conditions in thermodynamic processes, useful for engineering students studying fluid mechanics and thermodynamics.
