Challenge Problems

Push your limits with challenges.

Question 1

In a given location, the energy inputs were measured to be 800 W/m² and the ground heat flux at 50 W/m². Calculate evaporation using the Energy Budget Method if the latent heat of vaporization is 2.5 MJ/kg.

💡 Hint: Convert units accordingly and remember to apply effective conservation energy principles.

Question 2

You have data on actual vapor pressure at different times: 10 mm in the morning and 20 mm in the afternoon. Use Mayer's formula with a wind speed of 5 m/s to estimate the evaporation. Assume K = 0.5.

💡 Hint: Don’t forget to calculate the saturated vapor pressure based on temperature, which often influences morning and afternoon values.
