GEOG 1216 Lecture Notes - Sea Level, Water Vapor, Mecha

A watershed has a drainage area of 40 km^2. Annual average precipitation is 100 cm/yr. Studies show that average evapo-transpiration is to be 50% of the precipitation. Runoff collected and measured in a stream has average flow of 1.25 m^3/s. What is average infiltration rate in cm/yr?

How is water transferred from the air to the ground?

a. transpiration

b. precipitation

c. evaporation

d. all of the above

In exercising, a weight lifter loses 0.110 kg of water throughevaporation, the heat required to evaporate the water coming fromthe weight lifter's body. The work done in lifting weights is 1.30105 J.


-Assuming that the latent heat of vaporization of perspiration is2.42 106 J/kg, find the change in the internal energy of the weightlifter.
