Water flows in a horizontal, rectangular channel initially 10 feet wide and 2 feet deep. The initial velocity is 6 ft/s. This flow encounters downstream a simultaneous downward step and constriction. No energy losses are associated with these changes in channel configuration. a. What is the specific discharge, q: i. Upstream (for w= 10 feet)? ii. Downstream (for w = 6 feet)? b. What specific energy, E, is associated with the flow as initially specified (at the upstream location)? c. What is the minimum energy needed to pass the full discharge at the downstream location? d. What is the height (Az) of the smallest downward step necessary for the upstream flow conditions to remain as specified?
There is a reservoir covering a 500-hectare area that has a constant draft of water pumped from it. The reservoir has a constant inflow from an upstream watershed, where the annual rainfall is 550 mm and the annual runoff is 312 mm. Over a 30-day period, the reservoir depth drops 9.5 m. During this time, there was precipitation over the reservoir of 87 mm and the total evaporation was 73 mm. What is the daily draft of water from the reservoir (in hectare-meters)?

9.4. A small farm reservoir behaves as two identical CFSTRs in series. Flow into the reservoir consists of runoff from pasture land having an average BOD, of 50 g/m³ and an average flow rate of 0.5 m³/s. Volume of the reservoir is 2.16 x 106 m³. If k = 0.2 d-¹ and k, = 0.35 d-¹ at 20°C, determine the dissolved-oxygen concentration if the water temperature is 20°C, the inflow is anaerobic, and steady-state conditions exist.
