The wet bulb temperature lines, on the psychrometric chart, are curved lines.

The sensible heat factor during cooling and dehumidification process is given by (where h₁ = Enthalpy of air entering the cooling coil, h₂ = Enthalpy of air leaving the cooling coil, and h_A = Enthalpy of air at the end of dehumidification process)

Thermal diffusivity is a

The condition of refrigerant after leaving the compressor and before entering the condenser is superheated vapour.

The total radiation from a black body per second per unit area is __________ fourth power of the absolute temperature. This statement is known as Stefan-Boltzmann law.
