What does the Pan Evaporation Method estimate?
Think about the processes of water loss.
What does K_p stand for?
It adjusts the pan evaporation measurements.
What is the primary purpose of the Pan Evaporation Method?
Focus on the process of water loss to the atmosphere.
True or False: The pan coefficient (K_p) is a constant value.
Consider if external factors can change this value.
In an area with high winds and low humidity, the measured evaporation from a Class A pan is 12mm. If the average K_p for this environment is determined to be 0.6, what is the estimated ET?
Use the formula and consider how environmental factors play a role.
Investigate how an increase in temperature affects the K_p and subsequent ET estimates. Design a brief report discussing the relationship with supporting data.
Focus on how K_p changes with temperature.
