1.A researcher is conducting an evaporation study using a 5ft diameter evapoartion pan with 75lbs of water. Over the course of 3days, she added another 6lbs of water and at the end of 3days, there was 67lbs of water remaining. A nearby rain gage recorded 0.4 inches of precipitation over the period. What was the pan evaporation rate (in inches/day)?
2.At normal atmospheric conditions, approximately what pressure in psi must be applied to water 70 F to reduce its volume by 2 %?
