Given the following states find absolute humidity enthalpy d

Given the following states, find absolute humidity, enthalpy, dew point temperature, and specific volume of the air-. T = 15 degree C, phi = 0.60 T = 30 degree C, phi = 0.40 T = 45 degree C, phi = 0. 30

Solution

a)

Abvsolute humidity= 6.371 g/kg

Enthalpy=31.193 kJ/kg

D.temp=7.31 C

Specific volume=0.823 m3/kg

b)

Abvsolute humidity= 10.6 g/kg

Enthalpy=57.25 kJ/kg

D.temp=15 C

Specific volume=0.872 m3/kg

c)

Abvsolute humidity= 18.18 g/kg

Enthalpy=92.2 kJ/kg

D.temp=23.4 C

Specific volume=0.926 m3/kg
