| Wet Bulb Temperature Equation |
| The wet-bulb temperature, Twet, is a common humidity variable (e.g., Schwerdtfeger 1976, p 50ff.). A wetted thermometer will read lower than the ambient air temperature because of evaporation (but higher with condensation), and that rate of evaporation depends on the mixing ratio. |

| Fluid Mechanics and Machinery |
| The flow of ideal non-viscous fluids was extensively studied and mathematical theories were developed during the last century. The field of study was called as ‘Hydrodynamics’. However the results of mathematical analysis could not be applied directly to the flow of real fluids. |
