HEATING VENTILATING AIR CONDITIONING GUIDE 1941 Consider the total heat gain as that resulting from solar radiation and neglect the heat transmission through the glass caused by the difference between the temperatures of the inside and outside air.

HEATING VENTILATING AIR CONDITIONING GUIDE 1941 The left hand member of Equation 13 represents the total amount of available draft created by the pressure transformer, that is, the natural draft chimney, Venturi chimney, or fan, and is equal to the theoretical intensity less the internal losses incidental to operation.

HEATING VENTILATING AIR CONDITIONING GUIDE 1941 Because the low static pressures involved are usually less than % in. of water, disc or propeller fans are generally used instead of the blower or housed types.

HEATING VENTILATING AIR CONDITIONING COIDE 1941 Although it is possible under certain conditions to recognize the presence of particles smaller than 10 microns, the normal eye is unable to resolve any dimension under about 50 microns, and thus all air floated material of this kind is too small to identify without the aid of a micro scope.
