Challenge Problems

Push your limits with challenges.

Question 1

A recent study in a dry region used the Penman Equation to estimate ET during a drought. Given the net radiation was 200 W/m², soil heat flux was negligible, and the wind speed was 3 m/s with a vapor pressure deficit of 1 kPa, calculate the estimated ET.

💡 Hint: Carefully substitute the values into the Penman Equation.

Question 2

Consider a scenario where an increase in wind speed leads to a noticeable change in ET rates. Discuss how this reflects in the Penman Equation and propose potential strategies for mitigating water loss.

💡 Hint: Think about how physical barriers might influence wind dynamics.
