Pick out the wrong statement
(A) A horizontal line on the humidity chart indicates the temperature changes
at constant molal humidity
(B) When water is cooled from 80 to 70°C by exposure to the air with a wet
bulb temperature of 60°C, then both the approach & the range would be 10°C
(C) For unsaturated air-water vapor mixture at atmospheric conditions, the
wet bulb temperature & adiabatic cooling lines are the same
(D) Relative saturation of unsaturated mixture of water vapor & air cannot be
increased by either reducing the mixture temperature or by increasing the total
pressure
