Question 1.
What does Qn represent in the Energy Budget Method?
Show hintHide hint
Think about the overall energy balance.
Question 2.
What does the abbreviation Qe stand for?
Show hintHide hint
It relates to the evaporation process.
3Question 3.
What does the Energy Budget Method principally rely on?
- Wind speed measurements
- Heat flux analysis
- Water quality assessment
Show hintHide hint
Think about what drives energy movement.
4Question 4.
True or False: The Energy Budget Method requires less data than other methods.
- True
- False
Show hintHide hint
Consider the complexity of the calculations involved.
Question 5.
Consider a reservoir with a net radiation of 600 W/m², sensible heat loss of 250 W/m², and heat gained is 50 W/m². Calculate evaporation Qe, and what implications would an increase in net radiation have on water resource management?
Show hintHide hint
Apply the energy balance concept.
Question 6.
A research team is estimating evaporation from a water body and records net radiation of 400 W/m², a latent heat of vaporization of 2260 kJ/kg, and a water density of 1000 kg/m³. Determine the evaporation rate E in kg/m²/s.
