Calculate the air density (kg/cu.m.) from an open water surface with air temperature \( 22^{\circ} \mathrm{C} \), relative humidity is \( 40 \% \) and wind speed is \( 3 \mathrm{~m} / \mathrm{s} \), all measured at height \( 2 \mathrm{~m} \) above the water surface. Assume a roughness height of \( 0.03 \mathrm{~cm} \). The net radiation is \( 200 \mathrm{~W} / \mathrm{m}^{\wedge} 2 \) *Kelvin = Degree Celsius \( +273.2 \), use this in computing for the density of air
