An insulated rigid tank initially contains 1.4-kg
Chapter 4, Problem 127P(choose chapter or problem)
An insulated rigid tank initially contains 1.4-kg saturated liquid water at \(200^{\circ} \mathrm{C}\) and air. At this state, 25 percent of the volume is occupied by liquid water and the rest by air. Now an electric resistor placed in the tank is turned on, and the tank is observed to contain saturated water vapor after \(20 \mathrm{~min}\). Determine \((a)\) the volume of the tank, \((b)\) the final temperature, and \((c)\) the electric power rating of the resistor. Neglect energy added to the air.
