Rate of seepage per unit length of the dam (in m³/hr/m) Seepage velocity Quantity of seepage per day if the dam is 350 m long

Estimate the constant rate of withdrawal from a 1375 ha reservoir in a month of 30 days during which the reservoir level dropped by 0.75 m in spite of an average inflow into the reservoir of 500,000 m 3 /day. During the month the average seepage loss from the reservoir was 2.5 cm, total precipitation on the reservoir was 18.5 cm and the total evaporation was 9.5 cm.

5) Two water reservoirs are connected by a cast iron pipeline which is 150 mm in diameter for the first 6 m and 225 mm diameter for the remaining 15 m as shown in Figure 1. The entrance and exit are square-edged. If the discharge is 0.185 m³/s and dynamic viscosity of water is 0.00102 Ns/m², determine the various losses along the pipeline.

Estimate the constant rate of withdrawal from a 1375 ha reservoir in a month of 30 days during which thereservoir level dropped by 0.75 m in spite of an average inflow into the reservoir of 0.5 Mm^3/day. During themonth, the average seepage loss from the reservoir was 2.5 cm, total precipitation on the reservoir was 18.5 cmand the total evaporation was 9.5 cm.

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.

A lake with an area of 5 km2 has a net decrease in storage of 6 ha-mm. The inflowing stream rate is 2 m3/s while the outflow rate is 2.5 m³/s. If no rain fell during the month, what is the estimated total evaporation for the month? 2. (0.5. 36oor,24
