Review Questions Which of the following statements are true and which are false? temperature of the mixture. 6. The wet bulb temperature of an air-water vapor mixture is higher than the dry bulb temperature. 7. The wet bulb temperature of an air-water vapor mixture is approximately equal to the adiabatic saturation temperature. 8. During an adiabatic saturation process, the sensible heat of an air-water vapor mixture decreases but its latent heat increases. 9. The wet bulb temperature of an air-water vapor mixture is equal to the dry bulb temperature when the relative humidity is equal to 100%. 10. The dry bulb temperature of an air-water vapor mixture is equal to the dew point temperature when the relative humidity is equal to 100%. 11. When a saturated air-water vapor mixture is cooled, some water vapor will condense. 12. The humid heat of an air-water vapor mixture contains the sensible heat of dry air and the latent heat of the water vapor. 13. The humid volume of an air-water vapor mixture is equal to the inverse of the density of the mixture. 14. The properties of an air-water vapor mixture can be determined froma psychrometric chart if two independent property values are known. 15. Every psychrometric chart is drawn for a specific barometric pressure S. Yanniotis, Solving Problems in Food Engineering. Springer 2008 237
