Web3. Whirling Psychrometer: Temperature and relative humidity of the air in open and in the crop canopy at different heights can be measured with whirling psychrometer (Fig. 2.15). The dry and wet bulb thermometers are attached horizontally to a rectangular wooden frame and it can be rotated with handle. WebJul 17, 2015 · Now, use the formula for given specific humidity say W given as W = 0.622 ( p v p b − p v) p b = 0.622 p v W + p v Substitute the value of p b in the eq (1) to get the value of p v Then apply the formula of Relative Humidity ϕ as follows ϕ = p v p s Where, p v (partial pressure) & p s (saturation pressure at D.B.T.) are known.
