4 cards from this section. Quick, good the night before a test.
What does E represent in the Water Budget Method equation?
Look at the equation components we discussed.
True or False: The Energy Budget Method uses the principle of conservation of mass.
Think about energy dynamics discussed in class.
What method is used to estimate evaporation when direct measurement is impractical?
Think about the methods we discussed in class.
True or False: The Penman Equation only considers energy factors for estimating evaporation.
Recall which components the equation includes.
In a given location, the energy inputs were measured to be 800 W/m² and the ground heat flux at 50 W/m². Calculate evaporation using the Energy Budget Method if the latent heat of vaporization is 2.5 MJ/kg.
Convert units accordingly and remember to apply effective conservation energy principles.
You have data on actual vapor pressure at different times: 10 mm in the morning and 20 mm in the afternoon. Use Mayer's formula with a wind speed of 5 m/s to estimate the evaporation. Assume K = 0.5.
Don’t forget to calculate the saturated vapor pressure based on temperature, which often influences morning and afternoon values.
