What is Bowen's Formula?

The Bowen ratio is generally used to calculate heat lost (or gained) in a substance; it is the ratio of energy fluxes from one state to another by sensible heat and latent heating respectively.

How to Calculate Bowen’s Ratio?

Bowen’s Ratio calculator uses Bowen’s Ratio=Sensible heat transfer from water body/Water Density*Latent Heat of Evaporation*Evaporation from water body (mm/day) to calculate the Bowen’s Ratio, Bowen’s Ratio is defined as the ratio of sensible to latent heat fluxes at the surface obtained based on thermodynamic considerations. Bowen’s Ratio and is denoted by β symbol.

How to calculate Bowen’s Ratio using this online calculator? To use this online calculator for Bowen’s Ratio, enter Sensible heat transfer from water body (Ha), Water Density (WD), Latent Heat of Evaporation (L) and Evaporation from water body (mm/day) (E) and hit the calculate button. Here is how the Bowen’s Ratio calculation can be explained with given input values -> 0.096 = 2/1*6*0.008.

FAQ

What is Bowen’s Ratio?
Bowen’s Ratio is defined as the ratio of sensible to latent heat fluxes at the surface obtained based on thermodynamic considerations and is represented as β=Ha/WD*L*E or Bowen’s Ratio=Sensible heat transfer from water body/Water Density*Latent Heat of Evaporation*Evaporation from water body (mm/day) . Sensible Heat Transfer from Water Body, Water Density is mass per unit of water, Latent Heat of Evaporation is a physical property of a substance and Evaporation from water body (mm/day) is the process by which liquid water from an open water surface is converted directly to water vapor.
