Challenge Problems

Push your limits with challenges.

Question 1

A crop is situated in an area receiving Rs = 30 MJ/m2/day, has an albedo of 0.25, and experiences Rnl = 4 MJ/m2/day. Calculate the net radiation and discuss its implications for evapotranspiration potential.

💡 Hint: How does the energy balance impact the water cycle?

Question 2

In a region with high wind speeds, the saturation vapor pressure is determined to be 3.5 kPa, and the actual vapor pressure is 1.8 kPa. How does this affect the aerodynamic term and thus the overall evapotranspiration?

💡 Hint: Analyze the relationship between atmospheric conditions and evapotranspiration rates.
