Psychrometrics or psychrometry are terms used to describe
the field of engineering concerned with the determination
of physical and thermodynamic properties of gas-vapor
mixtures.

A psychrometric chart is a graph of the thermodynamic
properties of moist air at a constant pressure.

In the ω-t chart, the dry bulb temperature (DBT) t appears
as the abscissa (horizontal axis) and the humidity ratio
(ω) appear as the ordinate (vertical axis). A chart is
valid for a given air pressure (or elevation above sea
level). From any two of the six independent properties
(DBT, WBT, RH, humidity ratio, specific enthalpy, and
specific volume), the balance of the six can be reckoned.

PETROLEUM ENGINEERING - QUESTION 25.3 : Liquid octane has a density of 703 kilograms per cubic metre and molar mass of 114.23 grams per mole. Its specific heat capacity is 255.68 J / (mol K). (a) Find the energy in J needed to increase the temperature of 1 cubic metre of octane for 1 Kelvin. (b) At 20 degree Celsius, the solubility of liquid octane in water is 0.007 mg / L as stated in a handbook. For a mixture of 1 L of liquid octane and 1 L of water, prove by calculations that liquid octane is almost insoluble in water.

UNIT OPERATION - EXAMPLE 9.2 : A distillation column separates 10000 kg / hr of a mixture containing equal mass of benzene and toluene. The product D recovered from the condenser at the top of the column contains 95 % benzene, and the bottom W from the column contains 96 % toluene. The vapor V entering the condenser from the top of the column is 8000 kg / hr. A portion of the product from the condenser is returned to the column as reflux R, and the rest is withdrawn as the final product D. Assume that V, R, and D are identical in composition since V is condensed completely. Find the ratio of the amount refluxed R to the product withdrawn D. Hint : Solve the simultaneous equations as follow in order to find the answer (R / D) : 10000 = D + W; 10000 (0.5) = D (0.95) + W (0.04); 8000 = R + D.
