A water supply reservoir has an annual capacity of 27,000 acre-feet. The present population is 55,000, which is expected to increase to 120,000 in 20 years. In how many years will the city's needs exceed the reservoir's capacity? Assume arithmetic population growth and an average daily draft from the reservoir of 155 gallons per person. Disregard losses.

A new water supply main is being planned for a new city of 2 million population and average per capita water demand of 300 litres per day. The water source is located 50 km from the newly planned city at similar elevation as the city. Water is proposed to be conveyed using two number of 100 cm diameter cast iron pipeline in parallel. Assume water density of 1,000 kg/m3 and viscosity of 1.0 x 10-3 kg/m-s. Determine the following: a. The total head loss (in m) during this conveyance of water in each pipeline. Use Colebrook equation to calculate frictional factor. b. The total electrical power (in MW for both pipeline) required to pump this water over 50 km distance assuming combined pump-motor efficiency of 70%. c. If the maximum pressure allowed in the pipeline is 1 MPa, how many pump stations (minimum numbers) are required along the 50 km distance pipeline instead of just one large pump. d. If the two pipes are replaced by just one pipe, what should be the minimum diameter of the pipe…
A city has a current total population of 40,000 residents. The estimated design population is 55,000 at the end of a design period of 20 years. Determine the design average, peak, and minimum flow rates. Use the following data. Current daily average flow to the wastewater treatment plant Daily average I/I flow Hourly peak I/I flow = 18,400 m³/d = 80 Lpcd = 180 Lpcd A new junior college will attract 1500 nonresident students per day. The daily average wastewater flow is 50 Lpcd. A new industry will add a daily average flow of 900 m /d for a 24 h/d operation. An hourly peak flow of 1500 m’/d will occur during the day shift. The plant will be shut down one day a week. It is expected that 10% per capita reduction in wastewater flow will occur with the future population growth. The minimum to average flow ratio is 0.4 for the current dry weather wastewater flow.

Problem 1. A water supply reservoir has an annual capacity of 40 × 10^3 acre-ft. It is serving a city with a present population of 85,000, which is expected to increase to 150,000 in 25 years. How many years from now will the city's needs exceed the reservoir's capacity? Assume arithmetic growth of the population and an average daily draft from the reservoir of 175 gallons per person. Disregard the losses.
Problem 1.1. Answer the following questions based on your textbook reading and/or ancillary sources. Make sure to always cite your source. a) Where does Los Angeles get its water from? How much water comes from each source? For any external (non-local) sources, how is the surface water transported to Southern California? b) What is the long-term average precipitation rate of the global hydrologic cycle (in meters/year)? How does that compare to the driest and wettest places on Earth and to Los Angeles? c) How does the long-term global surface precipitation rate (in m/year) compare to the long-term global surface evaporation rate (m/year)?
