Theory (42 points) Please, answer the following questions 1. Mass transferred from a surface into a moving fluid is known as: Convective mass transfer 2. Which of the following is NOT an assumption when deriving eq. (1-79), p. 41, from the continuity equation: Equimolar counter diffusion 3- Steady-state diffusion in solids involving the jumping of molecules adsorbed on the pore walls, from one adsorption site to another based on surface concentration driving force is known as: Knudsen diffusion 4. F-type, mass-transfer coefficients are suitable for all these options but uniquely suitable for Concentrated gas and liquid phase solutions 5- The dimensionless group that is defined as the ratio of momentum diffusivity and mass diffusivity is known as: Schmidt Number 6. In tray towers, when none of the liquid reaches the downs spouts due to low liquid and gas rates is known as Flooding 7. The most common type of tray used in tray towers is: Sieve 8. The relation that best describes vapor-liquid equilibrium for dilute solutions is known as: Henry's law 9. The process where a gaseous solute is absorbed from its mixture with an inert gas by a liquid in which the salute is soluble is known as Absorption 10. Ponchon-Savarit is used mainly for batch distillation: false 11. CMO is a condition required for McCabe-Thiele 12. The light key/heavy key concept is used mainly in approximate methods in multicomponent distillation: true 13. The Rayleigh equation is used for minimum reflux calculation in in multicomponent distillation: false 14. Batch distillation and differential distillation are fully equivalent: true 15. Batch distillation and flash distillation are fully equivalent: false 16. Differential distillation and flash distillation are fully equivalent: false 17. Which of the following is NOT an assumption when using the McCabe-Thiele Method: Constant temperature 18. The equation Z-N.x does NOT apply to the design of the following operation: Absorption in tray towers 19. The use of mass-transfer relationships at local (point) level in the tray leads to the point efficiency 20. The AlchE mode is the most reliable ane to relate Eng to Eac true 21. A feature of the Armeaza-Ortega-Estévez model for tray efficiency is: all options mentioned here
