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

topjm [15]

Answer:

A = 2

B = 1

Explanation:

The atomic number of lithium is 3.

Its atomic mass is 7 amu.

It is present in group group 1.

It has one valance electron.

Lithium is alkali metal it form salts.

It is silvery soft metal. It has lowest density as compared to all other metals.

It react vigorously with water.

It is used in rechargeable batteries which are used in camera, mobile, laptops etc.

The electronic configuration of Li:

Li₃ = 1s² 2s¹

Thus,

A = 2

B = 1
