A measurement method of air movement and radiant temperature with dry and wet Kata thermometers

Dry and wet Kata thermometers have proven especially useful for calculating convective and radiative heat transfer coefficients for the movement of air in a uniform thermal environment, i.e., in a room. Measurements obtained with the Kata thermometer are compared with those obtained from a Globe thermometer in terms of accuracy. A formula is developed for the Kata thermometer (which can also, in some instances, be applied to the Globe thermometer) whereby a number of environmental parameters are taken into account, e.g., ambient air temperature, saturated vapor pressure, mean radiant temperature, air movement, etc.
