#### Solved: 1. The Colorado River Is Famous For The Solids Load It Carries. Based On Historical Averages, Assume The Flow Is 22,500 Cfs (cubic Feet Per Second) And The Suspended Solids Concentration Is 42

1. The Colorado River is famous for the solids load it carries. Based on historical averages, assume the flow is 22,500 cfs (cubic feet per second) and the suspended solids concentration is 4200 mg/L at the upstream end of Lake Powell (the reservoir behind Glen Canyon Dam). What is the solids loading rate to the lake? Express your answer in US (or "short") tons/day. 2. You have an e
