If the pumping plant has a 60% efficiency, how many kilowatt-hour energy is required to lift water 5 meters?An 800-square-kilometer basin recorded 50 cm of rainfall in a year. During that year, ET was 5 meters, and recharge by ponds to the groundwater was 2.5e^7 cubic meters. Domestic pumping was 35 cubic meters/day and underflow from the basin was a loss of 25 cm. What is the total change in storage in this basin (give the answer in cubic meters per year)?An irrigator desires to lift a stream of 30 lps a vertical height of 12 m. If the loss of head in the casing and pump results in a 62% over-all pump efficiency and the electric motor has an efficiency of 90%, how many kilowatts (kW) and Bhp will his motor needs? What is the required water power (kW) and water horsepower (Whp)?
- No wrong answer please. A city with population of 49 x 103 capita in a period of 27 years in advance. The current population is 25 x 103 capita with a daily water consumption of 21 x 103 m³/d. The current and existing water treatment plant (WTP) has design capacity (maximum) of 49 x 103 m/d. Using the arithmetic method in estimating the population of this city, find for how many years will this plant reach its design capacity.If conveyance efficiency is 80% how much is the amount lost if 10 liters/second is available at the source?If the rotational speed of a pump motor is reduced by 35%, what is the effect on the pump performance in terms of capacity, head, and power requirements?

Select one: a. 200 m3/hr b. 175 m3/hr c. 150 m3/hr d. 140 m3/hrA small community had a population of 65000 and 85000 in the census year of 1991 and 2001 respectively. Assuming a geometric growth rate and an average water consumption of 300lpcd, Calculate the design flow for the treatment plant and the transmission mains. Select an appropriate value of design period. I will report and downvote wrong answers) Gaziantep City has P2000=1,500,000, P2010=1,750,000 and (P.F.)day=1.6. The available maximum rate of water for GaziantepCity is 420,000 m3/day. Using the Turkish Bank of Provincy extrapolation:a) Find the year until when the available water would be sufficient to meet the demands of Gaziantep City during themaximum demand day.b) Find the capacity of the distribution reservoir in m3if it is designed for the sum of 45% of the average daily demand and afire discharge of 160 lt/s lasting 12 hours.
