A3-inch diameter water pipe carries a flow rate of 6 gallons per minute. The pipe is 100 feet long and has a gate valve, two 45-degree elbows, and a sudden c factor for the pipe is 0.02 and the minor loss coefficients for the gate valve, elbows, and contraction are 12, 1.5, and 0.5, respectively. Determine the head loss due to friction and minor losses in the pipe, assuming the water temperature is 68°F and the density of water is 62.4 b

Based on ONLY on the diagram below, how much energy is the pump adding to the system. The pressure gauge Reads 60 psi 20 feet 30 feet 5 feet 1 foot 2 feet

A confined aquifer has a differential drawdown (Ah) of 5 feet. The flow rate (Q) is measured to be 10 gpm. Calculate the transmissivity (T) of the aquifer in gpd/ft.

Match the term from the Clean Water Act with its corresponding definitions National Pollutant Discharge Elimination System (NPDES) Total Maximum Daily Load (TMDL) Best Available Technology (BAT) Point source pollution A The maximum amount of a pollutant that a water body can receive while still meeting water quality standards. B. A permit program that regulates the discharge of pollutants from point sources into the waters of the United States. C. A specific location, such as a pipe or ditch, from which pollutants are discharged into a water body. D. A technology or treatment method that is determined to be the most effective way to control pollutants based on factors such as cost and feasibility.

Each gate of the lock is 6 m high and is supported by two hinges placed on the top and bottom of the gate. When the gates are closed, they make an angle of 120º. The weight of the lock is 5 m. If the water levels are 4 m and 2 m upstream and downstream, respectively, determine the magnitude of forces on hinges due to the water pressure.

Question 5 A submerged sharp crested weir 0.8 m high stands clear across a channel having vertical sides and a width of 3 m. The depth of water in the channel of approach is 1.25 m and 10 m downstream from the weir, the depth of water is 1 m. Determine the discharge over the weir in liters per second. Take Cd as 0.6

Question 4 B A rectangular sharp crested weir is to be constructed in a testing station with a small stream in which the discharge varies from 50 liters/s and 1250 liters/s. Find the suitable length of the weir, if the minimum head to be measured is 50 mm and the maximum head on it does not exceed one-third of its length.

Water FR=? L=0.8 m Hinge H=2.0 m B Single Rigid Gate L₁=0.9 m Question 4 A The discharge over a trapezoidal weir is 1.315 m³/s. The crest length is 2 m and the sides are inclined at 75° 57'49" with the horizontal. Find the head on the weir in meters.

As a strategy of the Salahadin Government to extend the residency community in Tikrit City, there is a plan to provide water for a new residential area on the west side of Tikrit City, as shown in the map in Figure 1. The new residential area is exposed to have 25000 residences, three schools to serve 1000 students, and a Plaza Markt that can serve 2000 persons. The water will be supplied from a purification station installed on the Tigris River at an elevation equal to 130 m. The distance between the water purification station and the center of the new residential area is about 9.5 km, and the elevation of the city center is about 150 m. The required pressure in the new residential area center is 30 m. The available pipes in the market with their price are shown in Table 1. Also, the price for each 10-meter of pump head is 1500$. Your task as environmental engineers is to design a sustainable and economically viable water system, including the main pipeline and pump for the new…
