1. The problem statement, all variables and given/known data A 260 liter rigid tank contains saturated-liquid water at 185oC. A valve at the bottom of the tank is opened and water is allowed to escape from the tank. The valve remains opened until all of the water inside of the tank is vaporized completely. During this process, heat is transferred to the tank from a source at 514oC such that the temperature inside the tank remains constant. Is this process possible? 2. Relevant equations The energy balance equation 3. The attempt at a solution I tried solving the system itself using the equation, but am confused on proving if or not the process is possible or not. How do i do that?
