QUESTION:
A rigid, insulated container fitted with a paddle wheel contains 5 lb of water, initially at \(260^{\circ} \mathrm{F}\) and a quality of 60%. The water is stirred until the temperature is \(350^{\circ} \mathrm{F}\). For the water, determine (a) the work, in Btu, and (b) the amount of entropy produced, in \(\mathrm{Btu} /{ }^{\circ} \mathrm{R}\).
ANSWER:Step 1 of 3
We are required to calculate the work and the amount of entropy produced.
