Answer:
E = 7333.33 mm
Explanation:
The annual evapotranspiration (E) amount can be calculated using the water budget equation:
(1)
<u>Where</u>:
<em>P: is the precipitation = 2500 mm, </em>
<em>Q(in): is the water flow into the river of the farmland = 5 m³/s, </em>
<em>ΔS: is the change in water storage = 2.5x10⁶ m³, </em>
<em>Q(out): is the water flow out of the river of the farmland = 4 m³/s.</em>
<em>Δt: is the time interval = 1 year = 3.15x10⁷ s </em>
<em>A: is the surface area of the farmland = 6.0x10⁶ m² </em>
Solving equation (1) for ET we have:
Therefore, the annual evapotranspiration amount is 7333.33 mm.
