The absolute humidity at atmospheric pressure at 32 ° C is 0.015 kg water / kg dry air. Specify:a. Partial pressure of water vapor = kPab. Relative humidity =%c. Dew point temperature = (oc)

A fresh hot cup of coffee is 80.4°C and the room temperature is 20.2°C.  After 5 minutes, the temperature of the coffee is 73.8°C.  How long, in minutes, will it take for the coffee to be a reasonable drinking temperature of 60.7°C?

The result of air temperature measurement obtained dry ball temperature 37°C and wet ball temperature 27.5 °C. Using a graph of psychotry, determine the properties of the air as follows:a. RH : %B. Moisture content : kg of water / kg of airc. Specific volume : m3/kgd. Enthalpi : kJ/kgE. Condensation temperature : °CIf the air is within 162 m3 of space, specify theF. Weight of air (dry air and moisture) : Kgg. amount of water content in the room: kg
