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.

- 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$.
