Water tank for problem

10 For problem 3.9 derive the relationship for the adiabatic saturation curve for the system. 

11 A mixture is made from 20 lb of water at 40°F, 10 lb of ice at 32°F and 10 lb of steam at 250°F and 20 psia. Determine the final temperature of the mixture and the amount of steam that condenses. Assume the mixing process to occur adiabatically. 

12 Derive the equations for saturated volume, humid heat and the adiabatic cooling lines for the psychrometric chart. 

13 A 500-gallon water tank has a continuous feed and discharge rate of 10 gpm and 15 lb of NaCl are added to the tank in a batch method. The tank has uniform mixing to maintain a uniform salt concentration at all times. Estimate the amount of salt in the tank after 2 hours. 

14 A 6-ft-diameter tank, 12 ft tall, is filled to capacity with water. Determine the time it takes to drain the tank through a 2-inch-diameter bottom drain.
