1. A long siphon connected at the side near the bottom of the reservoir discharges water through a nozzle 200mm by 50 mm creating a jet. Various points were identified located along the siphon: Point A is located after the reservoir connection, Point B is 4 m above Point A, Point C is 3 m above Point A, and Point D is 1 m below Point A and located before the nozzle. Determine the flow in m3/s along the siphon and the pressure in kPa at Point A, Point B, Point C, and Point D. Consider that the level of the reservoir is same with Point C. Assume no head loss along the siphon.

Assume no head loss along the siphon.
2. Two interconnected pipes A and B with 300 mm and 200 mm diameter, respectively, carries a flow of 0.116 m3/s. Determine the velocity in m/s of pipe A and pipe B. If pipe B was replaced with 400 mm diameter, determine the velocity in m/s of pipe B.
3. The 500 mm diameter pipe conveys treated water to supply a municipality with a demand of 40 MLD. Determine the head loss in meter if the length of the pipe is 10 km considering that (a) friction factor f is 0.018, (b) Hazen-William coefficient C is 90, and (c) Mannings coefficient n is 0.015.
4. The pump station requires to lift the water requirement of the municipality. The total dynamic head requirement is 40 m. If the total head loss is 5 m, determine the power in kW required to reach the required elevation. If the efficiency of the pump is 80% determine the power required in kW.
5. The Water District plans to cross two parallel pipes along both sides of the bridge to augment the 400 mm transmission line. If the diameter of the two pipes are 200 mm and 250 mm, respectively, determine the total head loss in meter and the flow rate in m3/s along the two pipes. Consider that the flow is 25 MLD and the length of both pipes are 150 m.
