(2) The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water- soaked cloth (wet-bulb thermometer) over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature) and it is lower at lower humidity. It is defined as the temperature of a parcel of air cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat supplied by the parcel. A wet-bulb thermometer indicates a temperature close to the true (thermodynamic) wet-bulb temperature. The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only. Tw = Tatan[0.151977(RH% +8.313659)] + atan(T + RH%) - atan(RH% - 1.676331) + 0.003 918 38(RH%) 3/2 atan(0.023 101RH%) 4.686035. where T is the current temperature in Celsius of the parcel, RH% is the relative humidity in percentage, atan is the arctangent function. Please write a python program to calculate WBT with known temperature T and different relative humidity level, which are specified at 10%, 20%, ..., 90%, 100% levels using loops.
