Question 16
XE-ENAT2 marksNeeds review
In a heating and humidification process, dry air (d.a) with relative humidity of 10% at ambient temperature of 10°C is mixed with superheated steam at temperature ‘T’. The resultant mixture is at 25°C with relative humidity of 50%. The total pressure before and after the process remains the same at 102 kPa. The saturated pressure of water vapor (
) at 10°C and 25°C are 1.2281 kPa, and 3.1698 kPa, respectively. The specific humidity in grams of water vapor per kg of dry air, can be calculated using
, where
and
are the partial pressures of water vapor and dry air respectively. The quantity of steam in grams (rounded off to 2 decimal places) added per kg of dry air is ______________.Log in to check the answer
