A pump is used to carry water (T =60 oF and ν = 1.217×10-5 ft2/s) from a large tank (elevation of surface = 30 ft and at atmospheric pressure) through a pipe to the exit (elevation 60 ft) at a rate Q = 1.5 cfs as shown below. The pipe is made of cast iron (ε = 0.00085 ft). The pipe segment before the pump has length L = 500 ft (three horizontal sections of 160 ft each and two...

Problem #3: Biochemical Oxygen Demand (BOD) and Stream Quality A wastewater treatment plant designed for a community of 45,000 people has a flow of 100 gal/person/day and a BOD5 loading of 0.2 lb/person/day. The upstream characteristics of the receiving waters are: stream flow rate = 20 cfs and BOD5 = 2 mg/L The water quality standards require the in-stream BOD5 to be less than 7 mg/L in this stretch of the river. The minimum BOD removal efficiency that the treatment...

Part I. Indicate whether true or false (T or F). ____ Storm water detention ponds typically are designed to regulate the outflow peak rate at or below a single target value, such as the pre-development (pre-land use change) peak runoff rate for a specified return period event. Detention storage alters the peak but not the volume of the outflow hydrograph. _____ Typical rating curves for weirs are concave upward. Typical rating curves for orifices are concave downward. ____ A sediment...
