2 cards from this section. Quick, good the night before a test.
What does the term 'latent heat of vaporization' refer to?
Think of the energy involved in changing states.
Name one advantage of the Energy Budget Method.
Consider its grounding in thermodynamics.
What does Qₛ represent in the Energy Budget Method?
Think about where the energy comes from.
True or False: The Energy Budget Method is based solely on empirical data.
Consider the principles it uses.
A lake receives 500 W/m² of solar radiation, reflects 30%, and loses 20 W/m² to back radiation. The air is taking 15 W/m² of sensible heat, and the heat storage in the water is 5 W/m². Calculate the energy used in evaporation.
Use the balance equation carefully!
If the density of water is 1000 kg/m³ and the latent heat of vaporization is 2260 kJ/kg, determine the evaporation rate given that Q_e is 310 W/m².
Be precise with unit conversions!
