The question the group wishes to address is how the air temperature, water temperature, and wind velocity affects the evaporation of the Western Pond. We believe that with a warm water temperature and warm air temperature the most water evaporation will occur, cold air temperature and warm water temperaure will cause relatively less evaporation, and cold air temperature and cold water temperature will cause the least amount of evaporation. We belive that wind velocity will have a marginal effect. We will attempt to collect data from 9/21-11/25 and divide those two months into three specific time periods based on the following conditions:1.warm air temp. and warm water temp. 2. cold air temp and warm water temp. 3. cold air temp and cold water temp. On specific testing days we will collect data on air temperature, water temprature, wind velocity, and depth of the pond. Using data collected we will construct lab models to simulate conditions at Western pond and calculate the evaporation rate. After final data collections we will evaluate our findings and draw conclusions concerning our our hypothesis.
