On a warm summer day in Oslo, the temperature is 21 degree C and the relative humidity is 70%. What is the absolute humidity? Wh
lesya [120]

Explanation:

According to the psychrometric chart at dry bulb temperature of 21^{o}C and RH 70%, the absolute humidity = 0.011 kg/kg dry air

Formula to calculate humid volume is as follows.

       \nu_{H} m^{3}/kg dry air = \frac{22.41}{273}TK (\frac{1}{28.97} + \frac{1}{18.02}H)

                     = (2.83 \times 10^{-3} + 4.56 \times 10^{-3} H) T K

                     = (2.83 \times 10^{-3} + 4.56 \times 10^{-3} \times 0.011) \times 294

                       = 0.847 m^{3}/kg dry air

Hence, humid volume of air is 0.847 m^{3}/kg dry air.

Specific enthalpy of dry air  = specific heat capacity of dry air × dry bulb temperature

                    = 1.006 kJ/kg ^{o}C \times 21^{o}C

                    = 21.126 kJ/kg dry air

Hence, the specific enthalpy of the air is 21.126 kJ/kg dry air.

As per the psychrometric chart at given conditions wet bulb temperature = 17.5 ^{o}C

As per the psychrometric chart at given conditions dew point temperature = 15.5 ^{o}C

Base your answers on the graph below, which represents uniform cooling of a sample of a pure substance, starting as a gas. Solid
Karolina [17]

Answer:

D & E

Explanation:

I think this is dealing with latent heat and D & E would be the range where you will find solid and liquid phases in equilibrium, cuz it starts as gas at from A to B, B to C is gas and liquid equilibrium, C to D is liquid, D to E solid and liquid, and then E to F is solid.
