Relative humidity is given by (where pv = Partial pressure of water vapour, pb = Barometric pressure, ps = Pressure of saturated air, pd = Pressure at dry bulb temperature, pw = Saturation pressure corresponding to wet bulb temperature and $$\mu $$ = Degree of saturation)

Relative humidity is given by (where pv = Partial pressure of water vapour, pb = Barometric pressure, ps = Pressure of saturated air, pd = Pressure at dry bulb temperature, pw = Saturation pressure corresponding to wet bulb temperature and $$\mu $$ = Degree of saturation) Correct Answer $$\frac{\mu }{{1 - \left( {1 - \mu } \right)\frac{{{{\text{p}}_{\text{s}}}}}{{{{\text{p}}_{\text{b}}}}}}}$$

Relative humidity is given by $$\frac{\mu }{{1 - \left( {1 - \mu } \right)\frac{{{{\text{p}}_{\text{s}}}}}{{{{\text{p}}_{\text{b}}}}}}}$$
Where
pv = Partial pressure of water vapour,
pb = Barometric pressure,
ps = Pressure of saturated air,
pd = Pressure at dry bulb temperature,
pw = Saturation pressure corresponding to wet bulb temperature,
$$\mu $$ = Degree of saturation
