A student used a sling psychrometer to measure the humidity of the air. If the relative humidity was 65% and the dry bulb temper
nataly862011 [7]

Answer:

3° C

Explanation:

The dew point temperature is the temperature of the air to which the air must be cooled so as to become saturated with the water vapor.

Here it is given that the relative humidity in the air, RH=  is 65%

And the dry bulb temperature is T = 10° C

Therefore, the dew bulb temperature is,

 $Td= T - \frac{100-RH}{5}$

$Td= 10 - \frac{100-65}{5}$

       = 10 - 7

       = 3° C

So the dew point temperature is 3° C .

The sulfur dioxide (so2) stack-gas concentration from fossil-fuel combustion is 12 ppmv. determine the stack-gas so2 concentrati
sergejj [24]

The concentration of SO_{2} in the stack gas = 12 ppmv

That means 12 L of  SO_{2} is present per 10^{6} L gas

The given temperature is 273 K (0 C) and pressure is 1 atm. At these conditions, 1 mol of gas would occupy,

PV = nRT

(1 atm) (V) = (1 mol)(0.08206\frac{L.atm}{mol.K}) (273 K)

V = 22.4 L

1 mol SO_{2} occupies 22.4 L

Moles of SO_{2} = 12 L *\frac{1 mol}{22.4 L} = 0.5357 mol SO_{2}

Mass of  SO_{2} =0.5357 mol *\frac{64.06 g}{1 mol}  = 34.32 g SO_{2}  *\frac{10^{6} microgram}{1 g} =3.432 *10^{7}μg

Converting 10^{6} L to m^{3}:

10^{6} L *\frac{1 m^{3}}{1000 L} = 10^{3}   m^{3}

Calculating the concentration in μg/m^{3}:

\frac{3.432 * 10^{7} microgram}{10^{3} L}    = 3.432 * 10^{4}  microgram/m^{3}
