Question
Determine the evaporation rate (inches/day) from a reservoir if the wind speed V30= 15 mph,
the water surface temperature is 15°C, the overlying air has a temperature of 25°C, and the
relative humidity is 30%.
Use the Fitzgerald, Horton, and Lake Heffner equations.
May assume V=V30;
ew and ea are expressed in inches of Hg. Show detailed calculations as show during lecture.
Note: Negative E refers to zero evaporation.
Problem 2 (Textbook Problem #3-17)
Prepare a clean, large sketch of Figure 3-9 in the textbook. Determine the Phi-Index associated
with the storm history given in that figure if the total surface runoff from the basin is equal to a
water depth (uniformly spread across the basin) of 2 inches.
(Attach detailed calculations using ALL strips of areas from your sketch by adjusting the
location of the Phi-Index line; Repeat calculations for accuracy- No partial credit offered
without detailed calculations because of the nature of the problem).
