Bowen's Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Bowen’s Ratio = Sensible Heat Transfer from Water Body/(Water Density*Latent Heat of Evaporation*Daily Lake Evaporation)
β = H_a/(ρ_water*L*E_L)
This formula uses 5 Variables

Variables Used

Bowen’s Ratio - Bowen’s Ratio is generally used to calculate heat lost (or gained) in a substance.
Sensible Heat Transfer from Water Body - (Measured in Joule) - Sensible Heat Transfer from Water Body moves heat from warmer to colder objects by conduction when they are in direct contact.
Water Density - (Measured in Kilogram per Cubic Meter) - Water Density is mass per unit of water.
Latent Heat of Evaporation - (Measured in Joule per Kilogram) - Latent Heat of Evaporation is the heat released or absorbed when matter disintegrates, phase changes from liquid to gas or changing stage from fluid to gas stage at a consistent temperature.
Daily Lake Evaporation - (Measured in Meter) - Daily Lake Evaporation is the process by which water changes from a liquid to a gas or vapor.

STEP 1: Convert Input(s) to Base Unit

Sensible Heat Transfer from Water Body: 20 Joule --> 20 Joule No Conversion Required
Water Density: 1000 Kilogram per Cubic Meter --> 1000 Kilogram per Cubic Meter No Conversion Required
Latent Heat of Evaporation: 7 Joule per Kilogram --> 7 Joule per Kilogram No Conversion Required
Daily Lake Evaporation: 56 Millimeter --> 0.056 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

β = H_a/(ρ_water*L*E_L) --> 20/(1000*7*0.056)

Evaluating ... ...

β = 0.0510204081632653

STEP 3: Convert Result to Output's Unit

0.0510204081632653 --> No Conversion Required

FINAL ANSWER

0.0510204081632653 ≈ 0.05102 <-- Bowen’s Ratio

Evaporation from Energy Budget Method

Go Daily Lake Evaporation = (Net Heat Received by Water Surface-Heat Flux into the Ground-Head Stored in Water Body-Net Heat Conducted out system by Water Flow)/(Water Density*Latent Heat of Evaporation*(1+Bowen’s Ratio))

Energy Balance to Evaporating Surface for Period of One Day

Go Net Heat Received by Water Surface = Sensible Heat Transfer from Water Body+Heat Energy used up in Evaporation+Heat Flux into the Ground+Head Stored in Water Body+Net Heat Conducted out system by Water Flow

Bowen's Ratio

Go Bowen’s Ratio = Sensible Heat Transfer from Water Body/(Water Density*Latent Heat of Evaporation*Daily Lake Evaporation)

Heat Energy used up in Evaporation

Go Heat Energy used up in Evaporation = Water Density*Latent Heat of Evaporation*Daily Lake Evaporation

Bowen's Ratio Formula

Bowen’s Ratio = Sensible Heat Transfer from Water Body/(Water Density*Latent Heat of Evaporation*Daily Lake Evaporation)
β = H_a/(ρ_water*L*E_L)
