Q.

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 μ = Degree of saturation)

  • A0.622 Pv / (Pb - Pv)
  • Bμ/[1 - (1 - μ) (Ps/Pb)]
  • C[Pv (Pb - Pd)]/ [Pd (Pb - Pv)]
  • DNone of these
Correct Answer : (B)

μ/[1 - (1 - μ) (Ps/Pb)]
