PSYCHOMETRIC CHART
INTRODUCTION:PSYCHOMETRICS IS THE STUDY OF MOIST AIR.
THE PSYCHOMETRIC CHART IS A GRAPHIC REPRESENTATION OF THE THERMODYNAMICS AND THERMAL PROPERTIES OF MOIST AIR.
THE LATENT HEAT IN WATER VAPOR IS THE LARGEST OF ANY COMMON LIQUID.
AS A RESULT, THE SMALL AMOUNT OF WATER VAPOR IN THE AIR MIXTURE OFTEN CONTAINS THE MAJOR PART OF THE TOTAL ENERGY OF THE MIXTURE.

HUMIDITY RATIO:
THE AMOUNT OF WATER IN THE AIR AND IS MEASURED IN GRAINS (7000 GRAINS = ONE POUND) OR POUNDS PER POUND OF DRY AIR.
ALSO KNOW AS ABSOLUTE HUMIDITY.

LATENT HEAT:HEAT ASSOCIATED WITH THE CHANGE OF STATE OF THE MOISTURE IN AIR.
LATENT HEAT OF VAPORIZATION IS APPROXIMATELY 1000 BTU/LB OF WATER.
WHEN MOISTURE IS CONDENSED FROM AIR, THE AIR IS REDUCING ITS LATENT HEAT.
WHEN MOISTURE IS EVAPORATED INTO THE AIR, THE AIR IS INCREASING ITS LATENT HEAT.

ENTHALPY:A THERMAL PROPERTY INDICATING THE QUANTITY OF HEAT IN THE AIR EXPRESSED IN BTU/LB OF DRY AIR.
ENTHALPY REPRESENTS THE SUM OF THE LATENT AND SENSIBLE HEAT OF AIR.

SPECIFIC VOLUME:
SPECIFIC VOLUME IS THE RECIPROCAL OF DENSITY OR THE VOLUME/WEIGHT.
THESE LINES SHOW HOW THE DENSITY OF AIR VARIES AS ITS TEMPERATURE AND MOISTURE CONTENT VARIES.
SPECIFIC VOLUME IS A USEFUL QUANTITY IN AIR CONDITIONING CALCULATIONS .
