Scientific Foundation
The Transpiration Rate Calculator is built on a simplified Penman-Monteith model, a cornerstone of evapotranspiration research, as outlined in FAO-56 guidelines. This model calculates transpiration by accounting for energy balance, vapor pressure deficit, and aerodynamic and surface resistances. For example, research on maize indicates typical surface resistance values of 50–100 s/m, with transpiration rates peaking at moderate temperatures and low humidity. The calculator uses constants (e.g., air density = 1.2 kg/m³, psychrometric constant = 0.067 kPa/°C) derived from peer-reviewed studies, ensuring reliable and accurate results.
