A class A pan is maintained near a small lake to determine daily evaporation (see table). The level in the pan is observed at the end of every day. Water is added if the level falls near 7 in. For each day the difference in height level is calculated between the current and previous day, and the precipitation value is from the current day. Determine the daily lake evaporation if the pan coefficient is 0.70.

Refilled at this point to 8 inches
