Question

The drainage basin of the Delaware River encompasses about 35,500 km^2 (= 35 x 109 m^2). The average annual precipitation for the drainage area is about 44 inches/year (= ~1.1 m/yr) and the evaporation reaches 23 inches/year (= ~0.6 m/yr). What is the flow rate of total flow at the mouth of the Delaware Bay? your units must be in m^3/seconds

Answer 1

A hint: you are given the area, as well as the net amount of meters per year of rainfall (precipitation minus evaporation). If you multiply these, you'll get an answer in terms of m^3 per year. From there, you should be able to find the answer.
