1. A 1220 mm-diameter ISI pan, with a depth of 255 mm, was fully filled and was used to simulate the evaporation rate of a reservoir with a surface area of 230 hectares. After 24 hours, the depth of the water dropped 7 mm. What is the daily evaporation of the reservoir and the water evaporated from the reservoir for a month (1 month = 30 days).
