(Available in the library) Chapter 13  Eastop and McConkey; Applied Thermodynamics for Engineering Technologists; 5th Edition  Notes – on VUTela  VUTela – Video Lectures, Additional Notes, Previous Tests 1. Explain the following terms: (a) Saturation (as it applies to the air-water mixture in these problems) (b) Humidification (c) Dehumidification (d) Humidity (e) Percentage humidity (f) Relative percentage humidity (g) Wet bulb temperature (h) Dry bulb temperature (i) Dew point (j) Adiabatic saturation temperature (k) Saturated volume and humid volume (l) Humid heat (m) Sensible heat 2. Derive the equation to show the relationship between HP and HR 3. You have an air-water mixture that is at atmospheric pressure and a temperature of 300C, the mixture has a relative humidity of 67%.  Using the psychrometric chart determine the following: (a) (b) (c) (d) (e) (f) (g) (h) (i) (j) (k)

Humidity of the mixture Percentage humidity Wet bulb temperature Dry bulb temperature Adiabatic saturation temperature Dew point temperature Humid heat Sensible heat Humid volume Saturation volume The enthalpy of the mixture

 Calculate (l) Partial pressure of water vapor in the mixture (m) Partial pressure of the air in the mixture...
