Unformatted text preview: e by varying the percent excess air from 0 to 200 percent. Plot the exit temperature against the percent excess air, and discuss the results. 1681 1667 A two-phase mixture of ammonia and water is in equilibrium at 50C. If the composition of the vapor phase is 99 percent NH3 and 1 percent H2O by mole numbers, determine the composition of the liquid phase of this mixture. Saturation pressure of NH3 at 50C is 2033.5 kPa. 1668 Using the liquidvapor equilibrium diagram of an oxygennitrogen mixture, determine the composition of each phase at 80 K and 100 kPa. 1669 Using the liquidvapor equilibrium diagram of an oxygennitrogen mixture, determine the composition of each phase at 84 K and 100 kPa. 1670 Using the liquidvapor equilibrium diagram of an oxygennitrogen mixture at 100 kPa, determine the temperature at which the composition of the vapor phase is 79 percent N2 and 21 percent O2. Answer: 82 K 1671 Using the liquidvapor equilibrium diagram of an oxygennitrogen mixture at 100 kPa, determine the temperature at which the composition...
