Heat Energy used up in Evaporation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Heat Energy used up in Evaporation = Water Density*Latent Heat of Evaporation*Daily Lake Evaporation
H_e = ρ_water*L*E_L
This formula uses 4 Variables

Variables Used

Heat Energy used up in Evaporation - (Measured in Watt per Square Meter) - Heat Energy used up in Evaporation. When something evaporates it basically takes in heat and when it condenses it cools down by giving out the heat into the atmosphere.
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

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

H_e = ρ_water*L*E_L --> 1000*7*0.056

Evaluating ... ...

H_e = 392

STEP 3: Convert Result to Output's Unit

392 Watt per Square Meter --> No Conversion Required

FINAL ANSWER

392 Watt per Square Meter <-- Heat Energy used up in Evaporation

(Calculation completed in 00.004 seconds)

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

Heat Energy used up in Evaporation Formula

Heat Energy used up in Evaporation = Water Density*Latent Heat of Evaporation*Daily Lake Evaporation
H_e = ρ_water*L*E_L

What is Latent heat of Evaporation?

Latent heat of Evaporation is the energy used to change liquid to vapor. The temperature does not change during this process, so heat added goes directly into changing the state of the substance.
