2. An insulated, sealed tank that is 2 ft3 in volume holds 8 lb of water at 100F. A 1/4 hp stirrer mixes the water for 1 hour. What is the fraction vapor at the end of the hour? Assume all the energy from the motor enters the tank. For this problem you do not have to get a numerical solution. Instead list the following in this order: a. State what the system you select is. b. Specify open or closed. c. Draw a picture. d. Put all the known or calculated data on the picture in the proper place. e. Write down the energy balance (use the symbols in the text) and simplify it as much as possible. List each assumption in so doing. f. Calculate W g. Lists the equations with data introduced that you would use to solve the problem. h. Explain step by step how to solve the problem. 2.
