Using Meyer’s Formula, if you know that es = 20 kPa, ea = 10 kPa, and wind speed at 9m is 2 m/s, what is the estimated evaporation? (Assume K = 0.36)
💡 Hint: Break down the formula step by step.
In an area with 10 daylight hours and an average monthly temperature of 30°C, apply the Blaney-Criddle method to estimate evaporation.
💡 Hint: Calculate p based on an understanding of annual daylight hours.
