NUMERICALS ON PSYCHROMETRY| CALCULATION OF Specific Humidity, Relative Humidity, DPT, Enthalpy

The specific humidity of atmospheric air at 25℃ DBT and barometric pressure of 760 mm of Hg is 0.016 kg/kg of dry air. Determine the following without using Psychrometry chart. i) partial pressure of water vapour. (MU-May 2019, 8M) ii) Relative humidity iii) Dew point temperature iv) Specific enthalpy v) specific volume
